Discovery of reprogramming signature may help further stem cell-based regenerative medicine research

Wednesday, September 19th, 2012

Public release date: 18-Sep-2012 [ | E-mail | Share ]

LA JOLLA, CA---- Salk scientists have identified a unique molecular signature in induced pluripotent stem cells (iPSCs), "reprogrammed" cells that show great promise in regenerative medicine thanks to their ability to generate a range of body tissues.

In this week's Proceedings of the National Academy of Sciences, the Salk scientists and their collaborators at University of California, San Diego, report that there is a consistent, signature difference between embryonic and induced pluripotent stem cells. The findings could help overcome hurdles to using the induced stem cells in regenerative medicine.

"We believe that iPSCs hold a great potential for the treatment of human patients," says Juan Carlos Izpisua Belmonte, a professor in Salk's Gene Expression Laboratory and the senior author on the paper. "Yet we must thoroughly understand the molecular mechanisms governing their safety profile in order to be confident of their function in the human body. With the discovery of these small, yet apparent, epigenetic differences, we believe that we are now one step closer to that goal."

Embryonic stem cells (ESCs) are known for their "pluripotency," the ability to differentiate into nearly any cell in the body. Because of this ability, it has long been thought that ESCs would be ideal to customize for therapeutic uses. However, when ESCs mature into specific cell types, and are then transplanted into a patient, they may elicit immune responses, potentially causing the patient to reject the cells.

In 2006, scientists discovered how to revert mature cells, which had already differentiated into particular cell types, such as skin cells or hair cells, back into a pluripotent state. These "induced pluripotent stem cells" (iPSCs), which could be developed from the patient's own cells, would theoretically carry no risk of immune rejection.

However, scientists found that iPSCs had molecular differences from embryonic stem cells. Specifically, there were epigenetic changes, chemical modifications in DNA that might alter genetic activity. At certain points in the iPSC's genome, scientists could see the presence of different patterns of methyl groups when compared to the genomes of ESCs. It seemed these changes occurred randomly.

Izpisua Belmonte and his colleagues wanted to understand more about these differences. Were they truly random, or was there a discernable pattern?

Unlike previous studies, which had primarily analyzed iPSCs derived from only one mature type of cells (mainly connective tissue cells called fibroblasts), the Salk and UCSD researchers examined iPSCs derived from six different mature cell types to see if there were any commonalities. They discovered that while there were hundreds of unpredictable changes, there were some that remained consistent across the cell types: the same nine genes were associated with these common changes in all iPSCs.

Discovery of reprogramming signature may help overcome barriers to stem cell-based regenerative medicine

"We knew there were differences between iPSCs and ESCs," says Sergio Ruiz, first author of the paper, "We now have an identifying mark for what they are."

The therapeutic significance of these nine genes awaits further research. The importance of the current study is that it gives stem cells researchers a new and more precise understanding of iPSCs.

Regenerative Medicine Gets A Boost With Quick Printing Of 3D Microstructures

Monday, September 17th, 2012

September 16, 2012

Image Caption: NanoEngineering Professor Shaochen Chen has demonstrated the capability of printing three-dimensional blood vessels in mere seconds out of soft, biocompatible hydrogels. Being able to print blood vessels is essential to achieving the promise of regenerative medicine because it is how the body distributes oxygen and nutrients.

April Flowers for redOrbit.com Your Universe Online

Nanoengineers at the University of California, San Diego have created a new technology that has far-reaching implications for regenerative medicine. The results of the project have been reported in Advanced Materials.

The team has been able to fabricate, in seconds, microscale three-dimensional (3D) structures out of soft biocompatible hydrogels. This could lead to better systems for growing and studying cells, including stem cells, in the laboratory. In the long-term, the goal is to be able to print biological tissues for regenerative medicine. For example, repairing the damage caused by a heart attack by replacing it with tissue from a printer.

Professor Shaochen Chen developed this new biofabrication technology, called dynamic optical projection stereolithography (DOPsL). Current fabrication techniques, such as photolithography and micro-contact printing, are limited to generating simple geometries or 2D patterns. Stereolithography is best known for its ability to print large objects such as tools and car parts.

The difference between earlier stereolithography and DOPsL, Chen says, is in the micro- and nanoscale resolution required to print tissues that mimic natures fine-grained details, including blood vessels, which are essential for distributing nutrients and oxygen throughout the body. Without the ability to print vasculature, an engineered liver or kidney, for example, is useless in regenerative medicine. With DOPsL, Chens team was able to achieve more complex geometries common in nature such as flowers, spirals and hemispheres. Other current 3D fabrication techniques, such as two-photon photopolymerization, can take hours to fabricate a 3D part.

The system uses a computer projection system and precisely controlled micromirrors to shine light on a selected area of a solution containing photo-sensitive biopolymers and cells. This begins the solidification process, which forms one layer of solid structure at a time, but in a continuous fashion. The Obama administration in March launched a $1 billion investment in advanced manufacturing technologies, including creating the National Additive Manufacturing Innovation Institute with $30 million in federal funding to focus on 3D printing. The term additive manufacturing refers to the way 3D structures are built layering very thin materials.

The development of this new technology is part of a grant that Chen received from the National Institutes of Health (NIH). Chens research group focuses on fabrication of nanostructured biomaterials and nanophotonics for biomedical engineering.

Two lessons I learned this week.

Sunday, September 16th, 2012
Tweet 

I learned two valuable things this week I thought I'd pass on in a Friday afternoon post.  Actually strictly speaking these are likely things I've learned before but needed to re-learn or to be 'reminded' of their importance.
Please pardon a little stroll away from the typically strict focus on cell therapy -- but in a way that's the theme of today's post.
1.  Take time each week to read something from outside your specific profession or job focus.  
I'm not talking here about the importance of escaping in the evening with a fiction novel (also very important) but rather reading something professional but from well outside your area of focus.  Here are my examples.

I always read WIRED magazine.  Aside from GEN it's the only magazine I read.  Just reading something outside of cell therapy or biotech often infuses me with an idea that otherwise would have never occurred to me like the need for a cell therapy X Prize or cellular aggregates as microcarriers or tissue-engineered memory and processing devices or even just the conviction to better represent cell therapy to the broader world out there of scientists, engineers, journalists, policy-makers, or perhaps people with too much money looking to be inspired and wanting to make a difference.

Similarly, on a flight this week I reached into the seat pocket in front of me and discovered a recent copy of the Journal of the American Medical Association.  I read a fascinating article that has me excited about an idea for how we as a cell therapy industry might lead the way in addressing clinical trial and data transparency that would put our sector in a leadership position, lend the industry a much-needed spotlight, and has the potential to facilitate the kind of meta-analysis and data-mining that could only be done through data aggregation.  I believe the concept has the potential to be disproportionately significant for a sector defined by so many small, under-powered trials.
The idea may never see the light of day but the point is the source of the inspiration.  In order to 'think' outside the box one typically has to 'be' outside the box.  Lesson?  Spend some time outside your box.
2. It often takes something very small to make a disproportionately significant impact on someone.  
I was reminded recently through an exchange of simple kindnesses just how little it sometimes takes to make a big difference in someone's life.  For you what might be so easy to give might be of unparalleled value to someone for whom that is so unattainable.  
Lesson?  When the opportunity knocks for you to give something small or simple, take it.  This kind of charity almost always has the potential to be mre impactful than you might ever imagine.

CIRM Funds Six UC San Diego Stem Cell Researchers

Saturday, September 8th, 2012

Newswise The governing board of the California Institute for Regenerative Medicine (CIRM) has announced that six investigators from the University of California, San Diego Stem Cell Research program have received a total of more than $7 million in the latest round of CIRM funding. This brings UC San Diegos total to more than $128 million in CIRM funding since the first awards in 2006.

UC San Diego scientists funded by the newly announced CIRM Basic Biology Awards IV include Maike Sander, MD, professor of Pediatrics and Cellular and Molecular Medicine; Miles Wilkinson, PhD, professor, Division of Reproductive Endocrinology; Gene Yeo, PhD, MBA, assistant professor with the Department of Cellular and Molecular Medicine and the Institute for Genomic Medicine; George L. Sen, PhD, assistant professor of cellular and molecular medicine; David Traver, PhD, associate professor with the Department of Cellular and Molecular Medicine and Ananda Goldrath, PhD, associate professor in the Division of Biological Sciences.

Sander was awarded nearly $1.4 million for her proposal to define and characterize the key transcription factors necessary to promote maturation of human embryonic stem cell (hESC)-derived pancreatic progenitors into mature insulin-secreting beta cells. The loss of pancreatic beta cells in type 1 diabetes results in the absence of insulin secreted by the pancreas. The goal of this work is to enable scientists to one day produce an unlimited source of transplantable beta-cells for patients with diabetes.

Wilkinsons grant of $1.36 million will allow his lab to develop and test induced pluripotent stem cells (iPS cells) from patients with genetic mutations in a component of the pathway that results in intellectual disabilities. Many of these patients also have autism, attention-deficit disorders or schizophrenia. Directed towards understanding fundamental mechanisms by which all stem cells are maintained, his research has the potential to impact non-psychiatric disorders as well.

A grant of almost $1.4 million will fund Yeos research to help decode the mechanisms that underlie the single most frequent genetic mutation found to contribute to neurodegenerative diseases amyotrophic lateral sclerosis (ALS or Lou Gehrigs disease) and frontotemporal dementia (FTD). Yeo will generate iPSCs and differentiated motor neurons derived from patients with these mutations, then use genome-wide technologies to analyze these and normal cells and test strategies to rescue mutation-induced defects in iPSC-derived motor neurons.

Sen received a grant of just over $1 million to investigate how tissue specific stem and progenitor cells exist to replenish both healthy, normal tissue and for regeneration from a wound. Disease and aging deplete stem and progenitor cells, impeding the bodys ability to regenerate itself. Sens work aims to better understand the mechanisms of self-renewal and differentiation in epidermal (skin) stem cells. Imbalanced growth and differentiation of epidermal cells can lead to a variety of human skin disorders, including psoriasis and cancer.

Traver, who was awarded a CIRM grant of more than $1.3 million in collaboration with Thierry Jaffredo of the Universit Pierre et Marie Curie in Paris, studies hematopoietic stem cells. HSCs are rare, multipotent stem cells that give rise to all blood cell types, including red blood and immune cells. Travers lab investigates the genes and signaling pathways used by vertebrate embryos to create the first HSCs. An understanding of this developmental process has implications for producing restorative stem cell-based therapies for diseases like leukemia and congenital blood disorders. Currently, medical treatments using HSCs are hampered by cell shortages and finding compatible matches between donors and recipients.

Goldraths $1.16 million grant will help develop strategies to induce immunological tolerance to hESC-derived tissues and cells. Immune-mediated rejection of hESC-derived tissues remains a significant barrier to the promise of regenerative therapies. She proposes a novel approach to promote long-term acceptance of hESC-derived tissues by exploring the molecular pathways and immune cell types that mediate the induction of immune tolerance and pursuing additional targets that halt rejection of tissue grafts derived from these stem cells. If successful, this would increase the potential reach of cellular therapies by decreasing the undesirable side effects of generalized immune suppression.

The CIRM Basic Biology Awards are designed to fund investigations into the basic mechanisms underlying stem cell biology, cellular plasticity, and cellular differentiation. These awards will also fund the development and use human stem cell based models for exploring disease. According to CIRM, studies supported by these awards will form the foundation for future translational and clinical advances, enabling the realization of the full potential of human stem cells and reprogrammed cells for therapies and as tools for biomedical innovation.

CIRM was established in November 2004 with the passage of Proposition 71, the California Stem Cell Research and Cures Act. The statewide ballot measure provided $3 billion in funding for stem cell research at California universities and research institutions and called for the establishment of an entity to make grants and provide loans for stem cell research, research facilities, and other vital research opportunities.

StemCells, Inc. Awarded $20 Million From the California Institute for Regenerative Medicine for Alzheimer's Disease …

Friday, September 7th, 2012

NEWARK, Calif., Sept. 6, 2012 (GLOBE NEWSWIRE) -- StemCells, Inc. (STEM) today announced that the California Institute for Regenerative Medicine (CIRM) has approved an award to the Company for up to $20 million under CIRM's Disease Team Therapy Development Award program (RFA 10-05). The award is to fund preclinical development of StemCells' proprietary HuCNS-SC(R) product candidate (purified human neural stem cells) in Alzheimer's disease over a maximum four-year period, with the goal of filing an investigational new drug (IND) application for a clinical trial in that time. In July, CIRM approved a separate award to the Company under RFA 10-05 for up to $20 million to fund preclinical development of HuCNS-SC cells in cervical spinal cord injury.

"With the recent spate of late-stage clinical failures in Alzheimer's disease, it is clear that the field could benefit from alternative approaches to lessen the huge burden on families, caregivers and our healthcare system," commented Martin McGlynn, President and CEO of StemCells, Inc. "Our recently reported preclinical data, which showed that our neural stem cells restored memory and enhanced synaptic function in two animal models relevant to Alzheimer's disease, shows our approach has promise. We greatly appreciate the support from CIRM, which should help us accelerate our efforts to test our HuCNS-SC cells in Alzheimer's disease."

StemCells will evaluate its HuCNS-SC cells as a potential treatment for Alzheimer's disease in collaboration with Frank LaFerla, Ph.D., a world-renowned researcher in the field. Dr. LaFerla is Director of the University of California, Irvine (UCI) Institute for Memory Impairments and Neurological Disorders (UCI MIND), and Chancellor's Professor, Neurobiology and Behavior in the School of Biological Sciences at UCI.

Mr. McGlynn added, "CIRM's approval of two awards to StemCells illustrates the tremendous promise of our neural stem cell technology and the high degree of confidence in the world class team of scientists and clinicians who will be working to translate this technology into potential treatments and cures for these devastating diseases."

Cytomedix's AutoloGel System Highlighted in Two Presentations at the 4th Congress of the World Union of Wound Healing …

Thursday, September 6th, 2012

GAITHERSBURG, MD--(Marketwire -09/05/12)- Cytomedix, Inc. (CMXI), a fully integrated regenerative medicine company commercializing and developing innovative platelet and adult stem cell technologies for wound and tissue repair, today announced that the Company's AutoloGel System will be highlighted in an oral abstract and a poster presentation at the 4th Congress of the World Union of Wound Healing Societies (WUWHS 2012) being held from September 2-6, in Yokohama, Japan.

The AutoloGel System is a device for the production of autologous platelet rich plasma ("PRP") gel, and is the only PRP device cleared by the U.S. Food and Drug Administration ("FDA") for use in wound management.

"The Impact of Autologous Platelet Rich Plasma (PRP) Gel on Chronic Wounds" will be presented September 5th from 3:00 to 4:30 p.m. JST as part of the Tissue Engineering and Regenerative Medicines in Wound Healing session. The poster, OR 206, will be presented by Laura Parnell, MSc, CWS, Precision Consulting on behalf of Carelyn P. Fylling, RN, MSN, CWS, CLNC, Vice President of Professional Services of Cytomedix and lead author on the poster.

Key Study Findings (all data reflects mean outcomes)

The study concluded that AutoloGel PRP Gel "initiated rapid size reduction in long-standing non-healing wounds of multiple etiologies in multiple health care sites even in patients with compromised status."

In addition, Dr. Chugo Rinoie, DPM, ABPO, CWS, Chief of Podiatric Surgery, Wound Healing Center, Methodist Hospital of Southern California, Arcadia, Calif., and Medical Director, Millennia Wound Management, Inc., Los Angeles, will present Poster 125, entitled "Healing Complex, Severe Diabetic and Ischemic Wounds in Japan Using Platelet-Rich Plasma Gel" in the Exhibit Hall as part of the Diabetic Foot, Critical Limb Ischemia and Foot Care session.

"We are honored to have these two presentations of positive data in support of the use of AutoloGel to accelerate wound healing in a variety of chronic wounds selected for presentation at WUWHS 2012, as more than 1,200 abstracts were submitted for inclusion at this prestigious international Congress," noted Martin P. Rosendale, Chief Executive Officer of Cytomedix. "The data from these studies support and validate previous studies showing that AutoloGel significantly and reliably improves the rate of healing, speed and progress to healing as compared with previous experience with standard wound care alone. The complexity and co-morbidities associated with the wounds treated in these studies would have excluded them from any randomized controlled trial, making the findings from these real-world studies even more compelling."

"We believe we will continue to generate data such as these through the comprehensive collection of evidence we are undertaking through the Centers for Medicare and Medicaid Services' Coverage with Evidence Development program. We are confident such data will continue to strongly support the ongoing coverage for autologous PRP gel for the benefit of the various stakeholders in improving clinical wound care outcomes while lowering overall costs," added Mr. Rosendale.

About the Congress of the World Union of Wound Healing SocietyThe Congress of the World Union of Wound Healing Societies is held once every four years and provides an international forum for announcement of the latest research relating to wound healing that draws between 3,500 to 5,000 clinicians, researchers and professionals who serve the wound care markets around the world. The Congress also helps to ensure the exchange of information, the improvement and development of education, international person-to-person support and the promotion of industrial collaboration. The ultimate aim is to develop the field of wound healing. Despite the fact that "wounds" are a fundamental component and important target for surgery, there are still many factors that have yet to be clarified or fully understood.

Cytomedix's AutoloGel System Featured in Continuing Education Program at the Paralyzed Veterans of America Summit 2012

Tuesday, September 4th, 2012

GAITHERSBURG, MD--(Marketwire -09/04/12)- Cytomedix, Inc. (CMXI) (CMXI), a fully integrated regenerative medicine company commercializing and developing innovative platelet and adult stem cell technologies, today announced that the Company's AutoloGel System was highlighted in a continuing education program at the Paralyzed Veterans of America Summit 2012 held August 28 to 30 at the Paris Las Vegas Hotel.

The AutoloGel System is a device for the production of autologous platelet rich plasma ("PRP") gel, and is the only PRP device cleared by the U.S. Food and Drug Administration ("FDA") for use in wound management.

The program, titled, "Platelet Rich Plasma (PRP) Gel for Wounds on Persons with SCI," was delivered by Laurie Rappl, PT, DPT, CWS, Clinical Development Liaison for Cytomedix. Ms. Rappl's discussion addressed the underlying mechanisms of action that allow the Company's physiologically relevant concentration of PRP in the AutoloGel System to accelerate healing in recalcitrant wounds in patients with Spinal Cord Injuries ("SCI"), and highlighted the clinical data demonstrating rapid reduction in wound area and volume, as well as reduction of undermining and sinus tracts/tunnels in non-healing wounds in patients with SCI.

"The physiology of SCI -- such as decreased blood flow, blood pressure and blood supply -- causes impairment at every step of the wound healing process. A physiologically relevant concentration of PRP has been shown to improve healing in even the hardest to treat chronic wounds in SCI patients," noted Ms. Rappl.

"It is especially rewarding for Cytomedix to have a continuing education program highlighting the benefits of the AutoloGel System for the treatment of chronic wounds in SCI patients. Pressure ulcers and other chronic wounds are persistent medical challenges that compromise the health and quality-of-life for these paralyzed patients," stated Martin P. Rosendale, Chief Executive Officer of Cytomedix. "Our clinical data demonstrates how the AutoloGel System's physiologically relevant concentration of PRP can rapidly restart the healing process in complex and chronic wounds, including wounds that were recalcitrant to other treatments."

Are some cell counts too good to be true? Why some companies’ product data may mislead.

Sunday, September 2nd, 2012
Tweet 

This is a cautionary tale about the need for robust product characterization and release specifications for all cell therapy products.
Background
While our food often has a list of ingredients, our drugs don't.  We rely on our regulatory agencies to rule on the safety of our drugs.  These agencies require drug manufacturers to submit to them the composition of their therapeutic compounds and then to comply with the product specifications.  It is this composition and these specifications which formed the basis of the clinical data evaluated by the agency and upon which the marketing approval is based.  Any deviation from those specifications requires a submission to the regulatory agency for review. Any deviation without such a submission is punishable.   
At the manufacturing site, as products come off the line they are subjected to a panel of product release tests to ensure each batch complies with the product specifications.
Specification compliance is a direct function of the consistency of the raw and ancillary materials, equipment, and operating procedures used in the manufacturing process.



Cell therapies present unique challenges when complying with this paradigm for several reasons only two of which I will mention here.  Firstly, it is not possible to achieve the level of product purification as one might with other therapeutic products.  Secondly, the product characterization is at a cellular rather than molecular level.

Autologous cell therapies present another set of unique challenge in this paradigm because of the notable patient-to-patient variability where the patient is also the donor of the raw material.  This often means there is a wider tolerance of heterogeneity in the product but it still must be within what has been proven to the regulatory agency as a safe and effective range.  


In cases where an autologous cell therapy is centrally manufactured, they are most often subjected to product release testing similar to that described above.  One notable difference, particularly for fresh products, is that the products may be shipped to the clinic and even administered before the full panel of test results are obtained.  This wold be considered highly unusual (if ever acceptable) with other types of products but is tolerated because of the time-sensitivity of these products and their high safety profile.


In the case of autologous cell therapy products produced at the bedside there is often not the same kind of product release discipline.  Often the regulatory agencies deal with the product consistency and specification compliance issue by ensuring that the cell processing device used point-of-care is validated to ensure the cellular product output is always within a specified range shown to be clinically safe and effective.


The Varying Degree of Product Characterization/Specification of Autologous GTP Cell Therapy Products


However - and now I get to the point of this blog post - for cell-based products, procedures and/or devices/kits which are not mandated to be formally approved by a regulatory agency before they can be commercially marketed, there is no product specification rigor.  Compliance with the Good Tissue Practice regulations and guidance is deemed to ensure safety.  In the United States, cell-based products which are deemed to be "minimally manipulated" and intended for "homologous use" are typically allowed to go straight to market with no formal approval.  Safety and clinical data is not required but is practically necessary to support physician adoption and, where applicable, reimbursement.  


This means that for these products there is a great deal of variability in terms of how much rigor companies apply in characterizing their product and then ensuring that each batch complies with the specifications they themselves have determined to be safe and effective. Again, where such products are manufactured in a centralized facility the likelihood of some release testing is greater.  However, those companies relying on a point-of-care processing kit or device business model that has not been deemed to require formal market approval, rarely (if ever) include product release testing.


The common criticism of these companies is that they simply do not know what they are injecting into patients because of the combination of the patient-to-patient donor variability, the lack of any disciplined product characterization or dosing studies, and the absence of any product release testing.  


This criticism is not equally levied at all autologous GTP products or companies - even those relying on point-of-care processing.  Of course some companies care and do a lot to try to ensure their product is well-characterized and that each batch complies with product specifications. This may involve the use of product release tests but can also involve the combination of pre-market research into the product characterization, safety, and dosing along with validation of the device/kit output.  In this way a company can say that within a very small margin, the output will be within the product specifications the company knows is safe and efficacious.


However, in a rush to get their device/kit to market some companies appear to care very little about the cell product characterization, validation of the output of their device/kit, or tying this data to optimal dose.


More concerning are those companies that appear to provide such data but it is wrong or meaningless.  What follows appears to potentially be a case study of precisely this problem. 


The INCELL Study 


This week I came across a fascinating white paper from Incell Corporation analyzing the output of adipose tissue processing kits of MediVet-America apparently demonstrating the inaccuracy of their cell counts (a common type of cell therapy product characterization) and calling into the question the cell count claims of Intellicell Biosciences (New York, NY) and Adistem (Hong Kong).


At the heart of the critique is the claim that the cell counting (product characterization) techniques employed by these companies counts as cells things (namely acellular micelles) which are not cells.

I encourage you to read the white paper in its entirety.  They corresponding author told me to watch for one or more papers which they are preparing for submission to peer-reviewed publications shortly.  Presumably these will rely on a larger data set and perhaps test other methodologies or technologies.


For the purposes of this blog, I've pulled what I believe are the most salient excerpts below:

Intrigued by the high cell numbers  (5 to 20 million cells/gram)  reported by kit/device manufacturers such as MediVet-America (Lexington, KY), Intellicell  Biosciences (New York, NY), and Adistem, Ltd. (Hong Kong) in adipose stem cell therapy compared to other methods (e.g., 
Chung,Vidal, and Yoshimura), INCELL staff conducted a research study to  investigate the high apparent yield of stem cells.  This initial work was focused  on SVF cells from the MediVet Kit, which is marketed to isolate adiposederived canine SVF and stem cells.

The cell yields reported for the Medivet Kits are five to more than ten times higher than the yields routinely obtained by INCELL from freshly harvested human or animal adipose tissue using our adipose tissue processing methods.  These yields are also tenfold or higher than those reported in the literature by most academic researchers (Chung-canine, Vidal–equine, Yoshimura–human).  Since these  cell counts are used to support stem cell dosing recommendations and cell banking, it is important to better understand why the cell numbers are higher.

...

A comparative analytical study of three dog donors of adipose tissue was designed to evaluate the cell yields using the MediVet Kit as an example of this class of isolation system. All  kit procedures were followed as per the instructions provided.  A brief overview of the different cell counting methods used, and the resultant cell counts, observations and explanations of the results observed, are described below

....

This study shows that incorrect counting of adipose derived SVF cells and the subset of regenerative stem cells can subsequently result in inaccurate dosing, both in direct therapeutic applications and in cryostorage of cells for future use.  The DAPI-hemocytometer cell count (manual) was considered the most accurate, but there are various sources of technical difficulties that  can lead to incorrect  cell numbers. The nature of adipose tissue itself with variability in dissociation by enzymatic digestion can all contribute to the outcomes. Fat tissue has a propensity to form acellular micelles and oils upon tissue disruption. Processing methods or reagents (e.g., Solution E or lecithins) can generate micelles that may be  erroneously  counted as cells. Autofluorescence and dye trapping or uptake by the micelles can lead to very high inaccurate cell counts when automated cell counting is used. 


In this study the most inaccurate counting came from the Cellometer. When used according to kitrecommended guidelines and on-site training provided by Nexelcom for counting  cells by the MediVet procedure, the Cellometer overstated the DAPI-hemocytometer cell count by up to 20X or more. The Coulter Counter protocols also led to incorrect, high cell numbers. Although the cell counts were still a bit high, the authors recommend the NucleoCounter, or similar equipment, as more acceptable for automated counting.  The manual hemocytometer-DAPI method is the most accurate, but requires a highly experienced cell biologist or technician to make accurate counts and  is not suitable for routine clinical use. 

...

Other companies also have claims of very high cell numbers when their processes are used. Adistem, like MediVet, states they add an emulsifying agent to their kits to assist in cell release, and they also use a light activation system. Their kits were not tested in this study but it is possible that the high cell numbers reported by Adistem are also incorrect and result from the same problems highlighted in this paper for the MediVet procedure. Ultrasonic energy, which is commonly used to manufacture micellular  liposome  structures and to disrupt and lyse cells, is  another potentially problematic procedure for counting and verifying viable, regenerative cells.  Intellicell 3uses ultrasonic energy to release cells from adipose tissue, and it is possible that resultant micelles or cell fragments contribute to the higher than expected cell numbers.  This assumption could be verified with additional studies.  

In summary, the authors caution that great care must be taken when using kits and automated cell counting for stem cell dosing and cryobanking of cells intended for clinical use. Overestimated  cell numbers would be a major confounding source of variation when efficacy of stem cells injected are compared as doses based on cell number and when cryostored cells are aliquoted for use based on 

specific cell numbers as a treatment dose.  Hopefully, this study will lead to more  reproducible counting and processing methods being reported in the literature, more inter-study comparability of cell doses to clinical outcomes,  more industry diligence to support claims, and more accurate counting for dosing stem cell therapies to patients.

 In Conclusion

Despite some of their other challenges, Intellicell, MediVet-America, and AdiStem (and others) have scored credibility points with some of my colleagues who have been impressed by the fact that they have incorporated product release criterion and testing technologies into their business model where their peer companies have not bothered.  This credibility may be quickly eroded if it turns out the results of their cell counts have been misleading.  For now it is a word of caution to do your own due diligence and/or not to fall into a similar product development/characterization trap.  Meanwhile, we will watch for the peer-reviewed papers.

Are some cell counts too good to be true? Why some companies’ product data may mislead.

Sunday, September 2nd, 2012

This is a cautionary tale about the need for robust product characterization and release specifications for all cell therapy products.
Background
While our food often has a list of ingredients, our drugs don't.  We rely on our regulatory agencies to rule on the safety of our drugs.  These agencies require drug manufacturers to submit to them the composition of their therapeutic compounds and then to comply with the product specifications.  It is this composition and these specifications which formed the basis of the clinical data evaluated by the agency and upon which the marketing approval is based.  Any deviation from those specifications requires a submission to the regulatory agency for review. Any deviation without such a submission is punishable.   
At the manufacturing site, as products come off the line they are subjected to a panel of product release tests to ensure each batch complies with the product specifications.
Specification compliance is a direct function of the consistency of the raw and ancillary materials, equipment, and operating procedures used in the manufacturing process.



Cell therapies present unique challenges when complying with this paradigm for several reasons only two of which I will mention here.  Firstly, it is not possible to achieve the level of product purification as one might with other therapeutic products.  Secondly, the product characterization is at a cellular rather than molecular level.

Autologous cell therapies present another set of unique challenge in this paradigm because of the notable patient-to-patient variability where the patient is also the donor of the raw material.  This often means there is a wider tolerance of heterogeneity in the product but it still must be within what has been proven to the regulatory agency as a safe and effective range.

ACT Comments on U.S. Appeals’ Court’s Dismissal Ruling in Case Challenging Federal Funding of Embryonic Stem Cell …

Monday, August 27th, 2012

MARLBOROUGH, Mass.--(BUSINESS WIRE)--

Advanced Cell Technology, Inc. (ACT)(ACTC), a leader in the field of regenerative medicine, today issued a statement on the U.S. Appeals Courts ruling, upholding a lower courts dismissal of the case, Sherley v. Sebelius, 11-5241, U.S. Court of Appeals for the District of Columbia Circuit (Washington), on the permissibility of federal funding of embryonic stem cell research.

This court ruling should be of considerable benefit to ACT and our embryonic stem cell-based clinical programs, commented Gary Rabin, chairman and CEO. It effectively removes major speed bumps for the National Institutes of Health (NIH) in terms of approving the several stem cell lines that we have submitted for their consideration for funding. With Fridays decisive ruling, we expect that a number of our embryonic stem cell lines will be approved for funding in coming months.

Sherley v. Sebelius had sought to block the United States Health and Human Services Department and the NIH from spending federal funds for research with hESCs, contending that doing so would violate the Dickey-Wicker Amendment, a short rider attached to legislation passed in 1996.

This ruling removes a great deal of the ambiguity that has hampered legislative attempts to provide an efficient mechanism for federal funding of hESC research, continued Mr. Rabin. The path for legislators to enact such legislation has now been cleared, and in that case we are optimistic that there could be encouraging new developments in the legislative arena, as well, in coming months. We would certainly hope that our patented, proprietary embryo-safe single-cell blastomere technique would be a part of any such conversation. We feel that if we could educate more Americans about this technique, and how directly and effectively it addresses the various ethical objections to hESC research, that broad support for the technique and the field overall would quickly fall into place.

More commentary on Fridays court ruling will be posted today on Mr. RabinsChairmans blog.
