Advances in biotechnology, especially the revolution in exosome-based therapeutics, single-cell RNA sequencing (scRNA-Seq), and CRISPR technology1315, one of the major developments in genetic engineering, has made precise and effective genome editing possible, which opens new avenues for modified genetic material, leading to advances in a variety of fields such as biotechnology and medicine16,17. Regenerative medicine represents a novel and promising therapeutic approach for individuals with exhausted or nonexistent options for managing their medical condition. Research studies, such as identification, clinical trials, and therapeutic applications on stem-cell have been extensive in recent years because of promising results from preclinical research (Fig. 1). The process of bringing these novel medicinal items from laboratories to the market is governed by strict guidelines and directives issued by qualified regulatory bodies18. Stem cells can be obtained for tissue engineering and cell treatments from four primary sources. The stem cells primary sources are embryonic and fetal tissues, comprising the placenta (including the chorion and amnion), umbilical cord (Wharton jelly), and particular tissues inside the adult, such as blood, skin, skeletal muscle, fat, and bone marrow, and somatic cells that have undergone genetic reprogramming to become distinct from their original state, such as iPSCs19.

A timeline depicting the introduction of mesenchymal stem cells (MSCs), their early research, and their substantial application in clinical trials, immunoregulation, and disease treatment.

Through an extensive synthesis of recent biotechnological advancements, critical evaluations, and emerging technologies, this review offers a nuanced comprehension of the advantages, difficulties, and future trajectories of stem cell-based regenerative therapy. By examining the historical foundations, current landscape, and prospects, this study endeavors to serve as a guide for researchers, clinicians, and stakeholders in navigating the intricate terrain of stem-cell therapy.

An extensive examination of existing literature was performed using the Embase, Web of Science, PubMed, and Scopus databases. The terms stem cell therapy, medical revolution, biotechnology advancements, and clinical trial were used in the search. Only articles published in English were included in the search. We assessed the abstracts of each article to determine the relevance of the retrieved papers to the topic. Subsequently, every relevant paper (in vivo, in vitro, and human-based research) was selected as part of the study.

ESCs exhibit characteristics that distinguish them from each other in stem cell biology. Notably, their pluripotency, which is defined by distinct features to differentiate into any human body cell, makes them highly adaptable and has great therapeutic promise20. Additionally, ESCs have a notably high self-renewal capacity, which contributes to their sustained presence and functionality over extended periods21. Potential ESC sources include mice, nonhuman primates, and humans. They are isolated from the blastocysts inner cell mass before implantation22,23. Because they are pluripotent cells, they can produce various kinds of cells from fetuses and adults in vivo and in vitro2426. Two methods were employed to separate ESCs from blastocysts inner cell masses. Microsurgery is the most commonly used surgical approach. Mechanical dissection in the microscopic direction is used to isolate cells of the trophoblastic lineage from the rest of the cell mass. The second approach entails employing an antibody to target trophoblast lineage cells27,28.

Regarding potential applications, the pluripotent nature of ESCs opens avenues for significant contributions to tissue regeneration and repair. Their capacity to undergo differentiation into many cell lineages holds promise for treating degenerative conditions and injuries, making them pivotal players in regenerative medicine. Furthermore, ESCs serve as invaluable tools in disease modeling for research purposes29. By replicating specific cellular environments, researchers can discover more about the workings of various disorders, providing a framework for cellular disease research and aiding in the creation of focused therapies. The unique properties of ESCs are relevant to drug testing and development30. Because of their pluripotency, a variety of cell populations can be created to provide a more complete picture of human cellular responses. This capability is particularly valuable for evaluating drug efficacy and safety and provides a sophisticated model for preclinical testing. Consequently, the multifaceted potential of ESCs dramatically enhances our comprehension of biology, fostering medical research and shaping the landscape of therapeutic innovation31,32.

ASCs stand out in the realm of regenerative biology because of their distinctive properties and vital roles in maintaining tissue homeostasis33. Multipotency is the ability of cells to possess various potential fates or abilities to develop into a restricted, diverse array of cellular phenotypes34. ASCs are endogenous stem cells that are crucial for preserving the tissues structural integrity, like bone, skin, and blood. They are located in specific niches or tissue sections35. ASCs have been discovered in several tissues, including blood, stomach, muscle, skin, brain, and heart36. They are less potent than ESCs; however, they have demonstrated efficacy in disease treatment. They can be extracted and harvested from individuals and used for tissue regeneration through autologous or allogeneic transplantation37. ASCs have a more specialized differentiation capability than pluripotent cells, such as ESCs, and can help generate particular cell lineages within their original tissue34.

Stem cells function in repairing damaged tissues and maintenance is essential throughout an individuals lifespan38. The unique ability of ASCs to maintain tissue and exhibit multipotency lends itself to a variety of possible uses within the regenerative medicine field39. Tissue-specific regeneration and repair are among the most promising approaches. ASCs can be utilized to regenerate damaged or deteriorated tissues due to their presence in diverse tissues, including the bone marrow, skin, and muscle40. Their capacity to undergo cell type-specific differentiation that is relevant to their native tissues places them at the forefront of tailored regeneration techniques, offering potential treatment options for ailments ranging from degenerative illnesses unique to certain organs to musculoskeletal injuries41.

ASCs are an appealing therapeutic choice for degenerative diseases. Because of their functions in tissue repair and regeneration, they are desirable targets for therapies aimed at slowing the advancement of illnesses marked by cellular degeneration42. Through the utilization of the regenerative capacity of these cells, scientists and medical professionals have investigated ways to create novel treatments that target the root causes of degenerative illnesses with the aim of enhancing patient outcomes and quality of life43. Within the class of ASCs, hematopoietic stem cells are a specific subset essential for bone marrow transplantation44. The immune system and blood regeneration rely on hematopoietic stem cells (HSCs), which are essential due to their versatility in cell differentiation into various blood cell types45. The utilization of these cells in bone marrow transplants represents a cornerstone in hematological therapies, offering a curative approach for conditions like leukemia and other disorders affecting the blood and immune systems46,47. Transplantation of hematopoietic stem cells is a life-saving intervention that reinstates functional blood and immune cell populations in individuals with hematopoietic disorders48.

Embryonic stem cells are derived from the amniotic fluid, placenta, and umbilical cord and represent a unique category within the spectrum of stem cell types49. Fetal cells possess multipotent capabilities and can differentiate into a restricted type of cells50. These cells are distinctively derived from tissues associated with the prenatal and perinatal stages of development, indicating their specialized origin49. Notably, perinatal stem cells exhibit a hybrid nature, sharing characteristics analogous to those of adults and ESCs. Their dual features make them adaptable and potentially useful for various regenerative medicine applications51. Perinatal stem cells offer a noncontroversial and ethically sound reservoir for therapeutic purposes49. Their properties, which are reminiscent of those of ESCs and ASCs, contribute to their unique regenerative potential. Since these cells undergo cell differentiation into a wide variety of cells, tailored approaches for tissue regeneration and repair are possible52. Perinatal stem cells show promise in furthering regenerative medicine across a range of tissues in terms of prospective uses. They are important components in targeted tissue renewal because of their capacity to specialize in particular cell lineages52.

Moreover, its therapeutic potential can be extended to other conditions, such as cerebral palsy and diabetes. Perinatal stem cells offer a novel and innovative approach to the development of medicines tailored to address the complexities of these disorders by exploiting their regenerative properties and versatile differentiation capabilities53. One notable advantage of perinatal stem cells is their potential for allogeneic transplantation without eliciting immune rejection. The immunomodulatory characteristics of these cells make them well-suited for transplantation across different individuals, eliminating the need for a perfect match between the donor and recipient54. This opens new possibilities for allogeneic stem-cell therapies, providing a feasible and practical approach to transplantation procedures without the intricate challenges associated with immune compatibility.

In summary, perinatal stem cells signify a distinct and highly promising category of stem cells with hybrid properties. Their application in regenerative medicine, therapeutic interventions for specific conditions, and allogeneic transplantation underscore their potential to reshape the landscape of stem cell-based therapies.

The iPSCs represent a revolutionary category in stem-cell studies and are characterized by properties that mirror those of ESCs55. Several human and mouse investigations have utilized fibroblasts and skin cells as the primary sources of adult cells. It has been discovered that adult brain stem cells have been identified as the primary cell type in investigations of reprograming cells56. Another study reported that murine bone marrow mononuclear cells can be reprogrammed more effectively than mouse embryonic fibroblasts57. Notably, iPSCs and their embryonic counterparts possess the capacity to undergo pluripotency to differentiate into distinct kinds of specialized cells58. One important way to iPSCs is to distinguish them from ESCs by their source, in which in order to create iPSCs, adult cells are reprogrammed. This methodology provides a novel means of addressing ethical concerns regarding the use of ESCs in scientific investigation59. Personalized medicine could undergo significant transformations if adult cells are reprogrammed to become iPSCs. The advancement of individualized cellular therapeutics involves the process of cellular reprogramming for individual patients is one of the main uses of iPSCs60. The iPSCs have the remarkable ability to transform into a wide variety of disease-specific cell types during cell reprogramming. This personalized approach improves the integrity and efficiency of cell-based treatments and offers a potential path in order to treat numerous illnesses and traumas.

Furthermore, iPSCs play a pivotal role in disease modeling in personalized medicine61. The capacity to generate iPSCs from individuals with particular genetic conditions has enabled researchers to create in vitro disease models. These models are extremely invaluable tools for understanding disease mechanisms at the cellular level and enable the exploration of targeted therapeutic interventions62. iPSC-based disease modeling advances the field of personalized medicine by enabling a more accurate and customized approach to medical research, thus opening the door for customized treatments. Beyond illness modeling and customized treatments, iPSCs have a major impact on toxicity assessments and drug development63. The pluripotent characteristics of iPSCs allow the generation of diverse cellular phenotypes, providing a flexible platform for evaluating the safety and effectiveness of pharmaceuticals. iPSC-based assays offer a more thorough understanding of how pharmaceuticals interact with various cell types, which helps identify possible side effects and directs advancements in the creation of remedies that are both safer and more effective64.

In conclusion, iPSCs offer a revolutionary approach to stem-cell investigation, owing to their pluripotent characteristics and the origin of adult cell reprogramming. Their applications in patient-specific cell therapies, disease modeling for personalized medicine, and drug discovery underscore their potential to revolutionize medical treatment and contribute to advancements in personalized healthcare.

Stem cells secrete numerous factors and exosomes that are responsible for immunomodulatory, antiapoptotic, antibacterial, and microbial properties. In addition to the ability for repair, communication, and regeneration (Fig. 2).

The schematic diagram represents the mesenchymal stem cells mechanism of action and their interaction with immune cells, including differentiation, immunomodulation, antiapoptotic effects, exosome and microvesicle release, migration and homing, and matrix remodeling.

Stem cells immunomodulatory actions have undergone extensive research when contrasted with other stem cell types65,66. Stem cells have a role in suppressing acute-phase responses by suppressing excessive activation of macrophages and T cells and initiating the secretion of inflammatory cytokines. This could decrease the likelihood of a cytokine storm67. Toll-like receptors (TLRs) present in MSCs detect injury signals and initiate immunomodulatory responses68. MSCs exhibit immunomodulatory properties via paracrine activity and direct intercellular communication facilitated by several bioactive compounds like cytokines, chemokines, and growth factors. These molecules affect both adaptive and innate immunity. MSCs can prevent the activation of T-cells via several immunomodulatory substances, such as TGF-1, PGE2, and HLA-G5. They also utilize molecules that are linked to a membrane, such as VCAM-1, PD-L1, and Gal-169,70. MSCs regulate NK cell cytotoxicity by reducing the expression of IFN-71. Cytokines are crucial for preserving the ability of ESCs to reproduce. This is achieved through the action of a specific cytokine called leukemia inhibitory factor (LIF), which belongs to the class of cytokines known as interleukin-672. The iPSCs can modulate the immune system, as demonstrated through their capacity to suppress the rapid increase of responder T cells in modified combined leukocyte reactions in vitro73.

In addition, apoptosis serves as a protective process within the immunological response of the host to combat pathogens and has a crucial function in interactions between the host and pathogens71. MSCs can inhibit apoptosis, which may occur due to pathogens, low oxygen levels, mechanical stress, or radiation. For instance, the ability of MSCs to avoid cell death (antiapoptotic effects) has been investigated in cardiac ischemia, neurological conditions, and respiratory ailments74. In addition, during apoptosis caused by hypoxia, MSCs stimulate the expression of certain proteins, including HGF, VEGF, and TGF-1, with the potential to prevent endothelial cell death75. Additional variables contribute to the antiapoptotic effect of MSCs, such as IL-6 and IGF-1, which results in enhanced secretion of SFRP2 protein76.

Stem cells exert their antimicrobial activity by secreting molecules and direct cell-to-cell interactions, namely by releasing antimicrobial peptides (AMPs). The antimicrobial activities are carried out by specific AMPs like the family of lipocalins (Lcn2), hepcidin, and b-defensins (hBD-1, hBD-2, and hBD-3)77,78. Stem cells boost their antimicrobial activity by upregulating LL-37, a peptide that is stimulated by bacteria and inhibits bacterial growth79.

Regeneration and restoration of damaged tissues rely heavily on stem cells because of their distinctive ability to suppress aberrant immune responses, their capacity to transform into specific tissues, and produce certain substances that stimulate the hosts reparative and regenerative systems80. Furthermore, the micro-vesicles and exosomes generated from stem cells are important for stem-cell communication and regeneration. Lipids, proteins, nucleic acids, including RNA and micro RNA, and signaling molecules are among the many bioactive compounds that are transported within the extracellular vesicles (EVs) emitted by stem cells of the body81. Compounds secreted by stem cells facilitate tissue regeneration by promoting the growth and specialization of stem/progenitor cells in the immediate vicinity. In addition, they control the placement of molecules in the extracellular matrix, activate pathways that prevent scarring, and promote the development of new blood vessels82,83. MSCs release soluble paracrine factors, including ANGPT1, HGF, EGF, VEGF, KGF, PGE2, and interleukin-10 (IL10). These factors can improve the restoration of epithelial and endothelial cells84,85.

Recent years have seen remarkable progress in stem-cell research that has greatly expanded our comprehension of stem-cell biology86. One notable milestone was the elucidation of novel mechanisms governing stem cell fate decisions. Researchers have uncovered key signaling pathways and transcription factors that play pivotal roles in directing stem-cell differentiation87,88. A cellular communication system known as the Notch signaling pathway is vital for various physiological and developmental functions89. Researchers have demonstrated the significance of the Notch pathway in determining the outcome of cells by either promoting the renewal of cells or their differentiation into various types of stem cells, including ESCs90, PSCs91, HSCs92, NSCs93, and ISCs94. Other instances of the signaling pathways are the PI3k/AKT signaling95 and TGF- signaling96. A transcription factor known as NF-B controls the diverse functions of NF-B in stem cells and developmental processes97. These findings enhance stem cell manipulation capabilities for specific therapeutic purposes, offering unprecedented opportunities for targeted cell-based interventions98. Recent studies have explored the nuances of lineage commitment and cellular specialization within the framework of stem-cell development. Scientists have identified regulatory networks that govern stem cell differentiation into distinct cell types, shedding light on the molecular events that dictate cell fate99,100.

Researchers have also unveiled insights into the epigenetic modifications associated with reprogramming, enhancing our comprehension of the molecular mechanisms by which somatic cells transform into pluripotent states101. For example, studies proved that gene expression and cellular identity are influenced by changes in DNA methylation patterns during the formation of iPSCs102. Modification of histones through acetylation and methylation, which affect chromatin structure and gene regulation, also play significant roles in reprogramming. This new understanding of epigenetic pathways helps clarify the complex processes involved in pluripotency induction and cellular reprogramming.

These advancements have contributed to improvements in iPSC-based methods for pharmaceutical innovation, disease modeling, and customized regenerative medicine62. Another significant stride in stem-cell research pertains to the tissue regeneration field103.

Challenges include difficulties in recruitment due to the evolving clinical landscape, lack of preclinical data, and variations in stem-cell properties. Despite these hurdles, stem-cell therapy, especially considering advancements in organoid technology for better modeling of viral effects, has significant clinical potential142. Despite current limitations and technological challenges, the continuous advancement of stem-cell treatment offers optimism in the fight to preserve lives and improve treatment results for individuals with severe COVID-19 infection (Fig. 4).

Potential and mechanism of action of mesenchymal stem cell treatment for COVID-19 pneumonia using MSCs, which have immunoregulatory characteristics, can help control the cytokine storm and COVID-19 lung injury. Mesenchymal stromal cells (MSCs) play an important role in a number of processes, including preventing neutrophil infiltration and transforming hyperactivated T cells into regulatory T cells (Tregs). They also promote the production of anti-inflammatory cytokines, such as prostaglandin E2 (PGE2), transforming growth factor beta (TGF), indoleamine 2,3-dioxygenase (IDO), and interleukin 10 (IL-10). Nevertheless, MSCs play a crucial function by stimulating the synthesis of growth factors by endothelial and epithelial cells, which in turn inhibits fibrosis and boosts the infusion of alveolar fluid.

Regenerative medicine with stem cells has investigated significant capacity across diverse medical specialties, offering innovative solutions for previously challenging conditions143. Patients stem cells are harvested for autologous stem-cell treatment. Autologous stem cells that have been cultured are cultivated in the lab before transplantation. These cells have the potential to be categorized into modified and unmodified expanded autologous stem cells. Allogeneic stem cells are classified similarly to autologous stem cells, but they come from healthy donors18. Autologous stem cells can be readily acquired and do not cause immunological rejection after infusion. Allogeneic stem cells provide multiple benefits, including the ability to select a donor, availability from different sources, minimal likelihood of causing an immune response, and the convenience of being readily available. Allogeneic MSCs are also immunogenic, indicating that they can trigger an immunological response. These cells can generate a memory response in the immune system under specific circumstances144146.

Utilizing their unique regenerative stem-cell capacities, scientists aim to generate interventions that induce the natural regeneration and repair of diseased or impaired dental tissues, potentially revolutionizing the oral healthcare landscape210,211. This promising field of study in dentistry holds the potential to pave the way for novel therapeutic strategies that offer patients improved outcomes and enhanced oral health212.

In the domains of trauma and wound healing, intensive research efforts have focused on uncovering the regenerative processes of stem cells to address the complexities of chronic wounds, burns, and traumatic injuries213. Stem cells exhibit promising capabilities in fostering tissue regeneration and mitigating scarring by influencing cell differentiation and supporting repair mechanisms in damaged tissues214,215. This exploration of stem cell-based interventions aims to revolutionize conventional wound care approaches by fostering natural tissue regeneration, accelerating healing processes, and minimizing scarring, thereby offering renewed hope to patients with challenging wounds and traumatic injuries216. In the quest for more potent treatment approaches to enhance patient outcomes and accelerate recovery, the potential of stem cells in trauma and wound healing serves as a ray of hope217,218. Stem-cell regenerative medicine is a dynamic and expansive field, continuously expanding its applications across various medical disciplines to address a wide spectrum of health conditions and diseases219 (Table 2).

Stem-cell therapy is utilized in specific medical fields.

In addition, various types of stimulation have been utilized during stem-cell therapy to enhance differentiation proliferation and improve healing, such as shock wave stimulation242. MSCs are increasingly being acknowledged as valuable resources for various orthopedic applications, and radial shock waves have been shown to substantially enhance the development and regrowth of MSCs in a laboratory setting. Furthermore, this type of stimulation safely accelerates cartilage repair in living organisms, suggesting positive results for clinical applications243. IR is a type of high-energy radiation that has enough energy to dislodge firmly bound electrons from atoms, leading to the creation of ions. In addition to being a carcinogen, IR is also used as a therapeutic option for patients with cancer. However, there is increasing data showing that extranuclear components, such as mitochondria, play a significant role in the cellular response to IR, and the mitochondrial function of MSCs was observed to be considerably increased after 4h of exposure to ionizing radiation, as determined by measuring mitochondrial oxygen consumption244. Cell proliferation has been induced in many in vitro trials using a modest amount of laser therapy. Osteoblasts, lymphocytes, keratinocytes, and fibroblasts exhibit enhanced proliferation when exposed to laser irradiation245. Other types of stimulation include electrical stimulation to enhance stem-cell therapy in nerve regeneration242, electrical stimulation to promote cell differentiation and proliferation of fatal neuronal stem cells into neuronal stem cells246, and nonpeptide small molecules247, in addition to mechanical stimuli such as cyclic stretch, three forces, laminar shear stress, cyclic pressure248, and gamma radiation249.

Stem-cell studies have been significantly promoted by cutting-edge technologies that have revolutionized our understanding and utilization of these versatile cells. This discussion focuses on some of the most impactful biotechnological advancements in stem-cell studies, with a specific focus on exosome-based therapeutics, scRNA-Seq, and the revolutionary CRISPR-Cas9 gene-editing technology250252.

The new frontier of exosomes produced from stem cell-based therapeutics represents a promising avenue for the field of regenerative medicine253. RNAs, signaling molecules, and proteins are bioactive substances encapsulated in exosomes and small vessels secreted by stem cells. These nanovesicles are essential for intercellular interactions and can control a number of cellular functions254. Stem cell-derived exosomes exhibit unique properties that modulate immune responses, promote tissue regeneration, and foster repair mechanisms255. Harnessing the therapeutic potential of these exosomes holds considerable promise for developing innovative treatments for diverse medical conditions, including inflammatory disorders, neurodegenerative diseases, and tissue injuries253,256258. Stem cell-derived exosome-based therapies represent a burgeoning frontier in regenerative medicine, providing new opportunities for targeted, minimally invasive therapeutic interventions259.

Advances in scRNA-seq have allowed investigators to examine stem-cell transcriptomes individually, providing unprecedented insights into cellular heterogeneity and gene expression patterns13. This technology has played an essential role in comprehending the dynamics of stem-cell populations during differentiation and disease progression260,261.

With the advent of CRISPR-Cas9, a new era in gene editing has begun, which enables the precise modifications of stem-cell DNA14. Researchers can now edit or introduce specific genes with unprecedented accuracy, facilitating cancer and disease modeling, studying gene function, and developing potential therapeutic interventions262,263.

CRISPR-based technologies have enabled large-scale functional genomic studies and high-throughput screening of stem cells. That allows researchers to systematically interrogate gene function on a genome-wide scale, uncovering novel regulators of stem-cell fate, pluripotency, and differentiation264,265.

Beyond traditional CRISPR-Cas9, recent innovations, such as base editing and prime editing, offer enhanced precision in gene editing266. These techniques allow the modification of specific nucleotides without causing double-strand breaks, minimizing off-target effects and expanding the possibilities for therapeutic genome editing in stem cells267 (Fig. 6).

Immunotherapy chimeric antigen receptor (CAR) T-cell therapy can be filled with the help of recent developments in genome editing using CRISPR-Cas9. To enable robust, accurate, and controllable genetic alteration, genome editing techniques are used, such as base and prime editing. In both hematopoietic and non-hematopoietic cancers, T-cells can be circumvented through CRISPR-Cas9-induced multiplex deletion of inhibitory molecules, which enhances CAR T-cell growth and persistence. The use of targeted knock-in techniques during CAR T-cell engineering offers the possibility of producing highly effective and potent cell products. Lentivirus is viral particles modified to carry CRISPR components in T cells, CRISPR-Cas9 based on the precise insertion of CAR genes, more and strong CAR T-cells product engineered using CRISPR-Cas9 to overcome specific histocompatibility hurdles and with improved persistence/antitumor function could greatly improve the production of cellular immunotherapies and the therapeutic durability.

Overall, CRISPR-based gene editing shows great promise for therapeutic applications in stem cell-based regenerative medicine. This opens new avenues for correcting genetic mutations underlying various diseases, generating genetically modified cells for transplantation, and developing personalized cell therapies.

Stem cells are integral to the advancement of personalized medicine, aligned with the goal of tailoring healthcare to individual characteristics and encompassing genetic, environmental, and lifestyle factors16. From a patients cells, iPSCs provide a potent platform for building disease models that accurately reflect the persons genetic background268. This capability facilitates in-depth studies of disease mechanisms at the cellular and molecular levels, enabling more precise diagnosis and the establishment of targeted therapeutic strategies60. Moreover, modern gene-editing techniques, including CRISPR-Cas9, enable accurate alterations in stem-cell genomes269.

This breakthrough allowed the correction of genetic mutations associated with diseases, laying the groundwork for personalized therapies addressing specific genetic alterations in individual cells270. In pharmacogenomics, stem cells significantly contribute to the assessment of individual drug responses. Leveraging patient-derived stem cells in pharmacogenomic studies enables researchers to understand the impact of an individuals genetic composition on their reaction to various medications271. This knowledge serves as a guide for formulating personalized treatment plans, minimizing adverse reactions, and enhancing the overall therapeutic outcomes. Moreover, stem cells actively contribute to the identification of personalized biomarkers associated with specific diseases272. Differentiating patient-derived stem cells into cell types relevant to the disease makes it easier to identify molecular signatures that can be used as diagnostic indicators. These personalized biomarkers substantially improve the accuracy of disease detection and monitoring, marking a significant step toward more individualized and effective healthcare strategies273,274.

Stem-cell therapy is witnessing a surge in clinical trials, reflecting a growing interest in translating laboratory findings into viable treatments275. Clinical trials involving various stem-cell types are currently underway and include a wide range of health issues276. The goal of ongoing trials is to determine whether stem-cell therapies are effective in alleviating symptoms of neurological diseases such as Alzheimers, Parkinsons, and spinal cord injuries277 (Table 3). Researchers are investigating how stem cells might be able to repair damaged neurons, encourage brain regeneration, and lessen the symptoms of these crippling conditions288.

Examples of clinical trials with results involved in neurological diseases, cancer, cardiovascular, and Orthopedics, from http://clinicaltrials.gov/.

Clinical trials in cardiovascular medicine aim to evaluate the use of stem cells, such as progenitor cells and MSCs, for treating conditions like heart failure and ischemic heart disease. These trials explored the regenerative potential of stem cells in repairing impaired cardiac tissues and improving overall cardiac function289.

Research is now being conducted on stem cell-based therapeutics for cancer treatment, including studies focusing on HSC transplantation (SCT) to treat hematological malignancies290. In addition, researchers have explored potential applications for stem cells in conjunction with traditional cancer therapies in order to enhance therapeutic results and minimize negative consequences291. Additionally, clinical trials in orthopedics and musculoskeletal disorders involve the use of stem cells to treat conditions like osteoarthritis and bone defects. MSCs, which are known for their capacity to differentiate into bone and cartilage, are being studied for their regenerative potential in restoring joint and bone health292. Furthermore, stem-cell therapies are now under investigation for their potential applications to treat diabetes by replenishing pancreatic beta cells. Clinical trials have investigated the use of stem cell-derived insulin-producing cells as transplants to regulate blood glucose levels in patients with diabetes293.

Stem-cell therapy, although showing great promise, faces multiple obstacles and constraints that need to be carefully considered. One prominent challenge is the potential for tumorigenesis, wherein the number of transplanted stem cells may increase uncontrollably, leading to tumor formation294,295. The security of stem cells can only be ensured by thorough preclinical examinations before they can be used in clinical settings. Additionally, the immune response poses a challenge due to the recipients immune system perceiving the transplanted cells as alien, leading to rejection296,297. The development of strategies to mitigate immune rejection and improve engraftment remains an ongoing challenge.

Furthermore, precisely controlling stem cell development into the desired cell types is a significant challenge298. The variability in differentiation protocols and the possibility of off-target consequences raise concerns regarding the reliability and safety of the therapeutic outcomes. Additionally, scalability and cost-effectiveness in the production of sufficient quantities of quality-controlled stem cells for widespread clinical use remain logistic obstacles that must be overcome for the field to attain its full potential110,299,300.

Ethical considerations are central to the discourse surrounding stem-cell therapy, particularly the use of ESCs301. Discussions over the moral standing of the early human embryo arose because of the killing of embryos during the extraction of ESCs. Because of these concerns, scientists are looking at alternative sources of pluripotent stem cells, such as iPSCs, which are reprogrammed from adult cells and do not have the same ethical concerns as ESCs. Regulatory frameworks are essential for negotiating the moral challenges presented by different stem cell therapies302.

Countries have varying regulations governing the clinical utilization of stem cells, ranging from permissive to restrictive. Achieving a balance between promoting innovation and ensuring patient safety remains a challenge for regulatory bodies303. The evolving nature of stem-cell research and therapies necessitates dynamic regulatory frameworks that can be adapted for scientific advancement. Ongoing debates persist in this field, particularly regarding the commercialization of stem-cell therapies. Issues of accessibility, affordability, and equitable distribution of these therapies raise ethical questions.

Moreover, concerns regarding the premature marketing of unproven stem-cell therapies and the need for transparent communication regarding the state of scientific evidence contribute to the ethical complexity of this field304. In conclusion, addressing the difficulties and ethical considerations of stem-cell therapy requires a multidisciplinary approach that encompasses rigorous scientific research, transparent communication, and dynamic regulatory frameworks. Realizing the full promise of stem-cell therapies will require a careful balance between ethical responsibility and innovation as the field develops.

With the help of new technologies and the results of continuing research, stem-cell treatment might potentially transform many different areas of medicine. One key direction involves the integration of stem-cell therapy into precision medicine approaches, opening a new chapter in medical history, where customized care based on a persons genetic composition promises enhanced therapeutic outcomes and reduced side effects. Advances in genomics and the application of patient-specific stem cells are expected to drive this integration. Additionally, future research should focus on refining the immune modulation strategies associated with stem-cell therapies and addressing challenges such as immune rejection and graft-versus-host responses. Innovative approaches, including engineered stem cells and immunomodulatory molecules, aim to enhance compatibility with stem-cell treatment.

The continued evolution of gene-editing tools, including CRISPR-Cas9, will perform a key function in ensuring the precision and safety of stem-cell therapies. This technology enables the modification of specific genes in stem cells, offering avenues for targeted therapeutic interventions and correction of genetic disorders at the cellular level. The synergy between stem-cell therapy and bioengineering has emerged as a significant area of exploration. The integration of stem cells with advanced biomaterials can potentially create functional tissues and organs with improved structural and functional properties. Bioengineered constructs provide innovative solutions for tissue-specific regeneration and transplantation. These key directions underscore the multidimensional nature of future advancements in stem-cell therapy, bringing together precision medicine, immune modulation, gene editing, and bioengineering to propel the field toward transformative developments.

Recent developments in stem-cell therapy have illuminated a path of immense promise and transformative potential for revolutionizing modern medicine. The exploration of stem cells across diverse medical disciplines guided by advancements in science, biotechnology, and clinical trial applications has positioned this field at the forefront of biomedical research. The historical journey from foundational concepts laid by pioneering scientists in the late 19th and early 20th centuries to groundbreaking milestones such as the isolation of ESCs and the discovery of iPSCs underscores a monumental leap in medical science.

The regenerative processes of stem cells, categorized into embryonic, adult, induced pluripotent, and perinatal stem cells, offer unprecedented opportunities for therapeutic interventions. Development, tissue repair, and regeneration are all intricately linked to stem cells due to their remarkable capacity to differentiate into different cell types and self-renew. Their diverse applications include neurodegenerative disorders, cardiovascular ailments, spinal cord injuries, diabetes, and tissue damage, opening novel avenues for treating debilitating conditions. However, as the field advances, the critical challenges and complexities must be addressed. Problems like immunological rejection, tumorigenesis, and the precise manipulation of stem-cell behavior pose hurdles that demand comprehensive exploration and innovative solutions. The landscape of stem-cell therapy is intricate and requires a nuanced understanding of its historical foundations, current realities, and future trajectories.

In collating recent biotechnology advancements, critical trial evaluations, and emerging technologies, this review provides a comprehensive compass for clinicians, researchers, and stakeholders navigating the intricate terrain of stem-cell therapy. Future directions, marked by precision medicine integration, immune modulation strategies, advancements in gene-editing technologies, and synergy with bioengineering, offer a roadmap for the continued evolution of stem-cell therapies.

WHO launches new initiative to tackle the main cause of vision impairment

December 19th, 2024 2:50 am

The World Health Organization (WHO) is launching a new initiative, SPECS 2030, to assist countries in achieving the global eye care target of a 40% increase in the proportion of people with access to appropriate spectacles.

The launch will be held during a 2-day meeting in Geneva, Switzerland with over 100 participants including Member States representatives, UN agencies, academia and nongovernmental organizations.

"The SPECS 2030 initiative marks a significant milestone in combatting uncorrected refractive error, commonly known as short-sightedness or long-sightedness, which is the leading cause of vision impairment in both children and adults, said Dr Bente Mikkelsen, WHO Director for Noncommunicable Diseases, Rehabilitation and Disability. Globally, it is estimated that only around one third of people with vision impairment due to refractive error have access to a pair of spectacles that allows them to see well.

The SPECS 2030 initiative calls for coordinated action across 5 key pillars:

The initiative will focus on 4 key strategies of engagement to support countries and stakeholders.

We are committed to strengthen engagement with all key stakeholders and unite towards coordinated action and advocacy, said Dr Mikkelsen. To achieve this, the WHOGlobal SPECS Network has been established and the inaugural 32 member organizations are participating in the meeting.
