Tampa, FL (PRWEB) January 06, 2015
One million Americans experience acute myocardial infarctions, commonly known as a heart attack, each year and of those, approximately 300,000 to 500,000 individuals develop heart failure. A heart attack occurs when blood stops flowing properly to a part of the heart and the heart muscle is injured and can die because it is not receiving enough oxygen.
Cryo-Cell International has agreed to provide the Center with cord blood collections that have previously been donated to Cryo-Cell International by parents and designated for research use to advance regenerative medicine. These cord blood collections will allow the Centers scientists to continue to investigate the mechanisms whereby stem cells can be beneficial in limiting damage from heart attacks. A team at the Center, led by researcher and cardiology specialist, Robert J. Henning, M.D., has demonstrated in research animals that stem cells obtained from human umbilical cord blood can release a large number of biologically active growth factors and anti-inflammatory chemicals that can limit the substantial heart inflammation, cell injury and cell destruction that occurs with acute heart attacks, significantly reducing the effects of heart attacks, even when administered up to 24 hours after the heart attack.
We are making good progress in our studies thanks to the cord blood stem cells contributed by Cryo-Cell International, reports Henning.
Cryo-Cell International and others have demonstrated that human umbilical cord blood stem cells can be preserved for more than 20 years without loss of cell viability or potency. Consequently, parents who have the foresight to use cord blood banking services upon their babys birth can potentially use these cord blood stem cells years later to provide a regenerative treatment for a family member if an acute heart attack occurs. The Centers scientists hope to bring umbilical cord blood stem cell therapy to the treatment of patients who have experienced heart attacks within the next five years.
Heart disease is still the number one leading cause of death in the United States. We feel very fortunate that we can provide a valuable and consistent source of cord blood banked stem cells to the Center for Cardiovascular Research, said David Portnoy, Chairman and Co-CEO of Cryo-Cell International.

UC Irvine scientists studying the role of circadian rhythms in skin stem cells found that this clock plays a key role in coordinating daily metabolic cycles and cell division.
Their research, which appears Jan. 6 in Cell Reports, shows for the first time how the body's intrinsic day-night cycles protect and nurture stem cell differentiation. Furthermore, this work offers novel insights into a mechanism whereby an out of synch circadian clock can contribute to accelerated skin aging and cancers.
Bogi Andersen, professor of biological chemistry and medicine, and Enrico Gratton, professor of biomedical engineering, focused their efforts on the epidermis, the outermost protective layer of the skin that is maintained and healed by long-lived stem cells.
While the role of the circadian clock in processes such as sleep, feeding behavior and metabolism linked to feeding and fasting are well known, much less is known about whether the circadian clock also regulates stem cell function.
The researchers used novel two-photon excitation and fluorescence lifetime imaging microscopy in Laboratory of Fluorescence Dynamics in UCI's Department of Biomedical Engineering to make sensitive and quantitative measurements of the metabolic state of single cells within the native microenvironment of living tissue.
They discovered that the circadian clock regulates one form of intermediary metabolism in these stem cells, referred to as oxidative phosphorylation. This type of metabolism creates oxygen radicals that can damage DNA and other components of the cell. In fact, one theory of aging posits that aging is caused by the accumulative damage from metabolism-generated oxygen radicals in stem cells.
The Andersen-Gratton study also revealed that the circadian clock within stem cells shifts the timing of cell division such that the stages of the cell division cycle that are most sensitive to DNA damage are avoided during times of maximum oxidative phosphorylation.
Other studies in animals have linked aging to disruption of circadian rhythms, and Andersen said that accelerated aging could be caused by asynchrony in the metabolism and cell proliferation cycles in stem cells.
"Our studies were conducted in mice, but the greater implication of the work relates to the fact that circadian disruption is very common in modern society, and one consequence of such disruption could be abnormal function of stem cells and accelerated aging," he said.
Andersen adds that it is possible that future studies could advance therapeutic insights from this research.

Gamida Cell, a leader in cell therapy technologies and products for transplantation and adaptive immune therapy, announced that orphan drug designation has been granted by The US Department of Health and Human Services, The FDA Office of Orphan Products Development (OOPD) for the investigational medicinal product NiCord for the treatment of acute lymphoblastic leukemia (ALL), acute myeloid leukemia (AML), Hodgkin lymphoma and myelodysplastic syndrome (MDS).
The FDA orphan drug designation coincides with the positive opinion of the European Medicines Agency's (EMA's) Committee for Orphan Medicinal Products (COMP) regarding NiCord as a treatment for AML. Gamida Cell intends to file for NiCord orphan drug status with the EMA for other indications as well.
"Receipt of orphan drug status for NiCord in the US and Europe advances Gamida Cell's commercialization plans a major step further, as both afford significant advantages. We very much appreciate the positive feedback and support of the FDA and EMA and look forward to continuing what has been a very positive dialogue with these important agencies," said Gamida Cell president and CEO Dr. Yael Margolin.
The FDA and EMA grant an orphan drug designation to promote the development of products that demonstrate promise for the treatment of rare diseases or conditions. Orphan drug designation provides for various regulatory and economic benefits, including seven years of market exclusivity in the U.S. and 10 years in the EU.
NiCord is derived from a single cord blood unit which has been expanded in culture and enriched with stem cells using Gamida Cell's proprietary NAM technology.
It is currently being tested in a Phase I/II study as an investigational therapeutic treatment for hematological malignancies such as leukemia and lymphoma. In this study, NiCord is being used as the sole stem cell source.

Newswise In a groundbreaking study that provides scientists with a critical new understanding of stem cell development and its role in disease, UCLA researchers at the Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research led by Dr. Kathrin Plath, professor of biological chemistry, have established a first-of-its-kind methodology that defines the unique stages by which specialized cells are reprogrammed into stem cells that resemble those found in the embryo.
The study was published online ahead of print in the journal Cell.
Induced pluripotent stem cells (known as iPSCs) are similar to human embryonic stem cells in that both cell types have the unique ability to self-renew and have the flexibility to become any cell in the human body. iPSC cells, however, are generated by reprogramming skin or blood cells and do not require an embryo.
Reprogramming is a long process (about one to two weeks) and largely inefficient, with typically less than one percent of the primary skin or blood cells successfully completing the journey to becoming an iPSC. The exact stages a cell goes through during the reprogramming process are also not well understood. This knowledge is important, as iPSCs hold great promise in the field of regenerative medicine, as they can provide a single source of patient-specific cells to replace those lost to injury or disease. They can also be used to create novel disease models from which new drugs and therapies can be developed.
This research has broad impact, because by deepening our understanding of cell reprogramming we have the potential to improve disease modeling and the generation of better sources of patient-specific specialized cells suitable for replacement therapy, said Plath. This can ultimately benefit patients with new and better treatments for a wide range of diseases.
Drs. Vincent Pasque and Jason Tchieu, postdoctoral fellows in the lab of Dr. Plath and co-first authors of the study, developed a roadmap of the reprogramming process using detailed time-course analyses. They induced the reprogramming of skin cells into iPSC, then observed and analyzed on a daily basis or every other day the process of transformation at the single-cell level. The data were collected and recorded over a period of up to two weeks.
Plaths team found that the changes that happen in cells during reprogramming occur in a sequential stage-by-stage manner, and that importantly, the stages were the same across all the different reprogramming systems and different cell types analyzed.
The exact stage of reprogramming of any cell can now be determined, said Pasque. This study signals a big change in thinking, because it provides simple and efficient tools for scientists to study stem cell creation in a stage-by-stage manner. Most studies to date ignore the stages of reprogramming, but we can now seek to better understand the entire process on both a macro and micro level.

Scientists Develop Pioneering Method to Define Stages of Stem Cell Reprogramming

Plath's team further discovered that the stages of reprogramming to iPSC are different from what was expected. They found that it is not simply the reversed sequence of stages of embryo development. Some steps are reversed in the expected order; others do not actually happen in the exact reverse order and resist a change until late during reprogramming to iPSCs.
"This reflects how cells do not like to change from one specialized cell type to another and resist a change in cell identity," said Pasque. "Resistance to reprogramming also helps to explain why reprogramming takes place only in a very small proportion of the starting cells."

The Irvine Stem Cell Treatment Center announces a series of free public seminars on the use of adult stem cells for various degenerative and inflammatory conditions. They will be provided by Dr. Thomas A. Gionis, Surgeon-in-Chief.
The seminars will be held on Sunday, January 11, 2015, at 2:30pm and 4:30pm at Marie Callenders Grill, 12489 Seal Beach Blvd., Seal Beach, CA 90740; Tuesday, January 13, 2015, at 2:00pm and 4:00pm at Pollys Pies, 23701 Moulton Parkway, Laguna Hills, CA 92653; Friday, January 16, 2015, at 1:30pm and 3:30pm at Marie Callenders Grill, 12489 Seal Beach Blvd., Seal Beach, CA 90740; Saturday, January 17, 2015, at 2:30pm and 4:30pm at Dennys Restaurant, 23515 El Toro Road, Lake Forest, CA 92630. Please RSVP at (949) 679-3889.
The Irvine Stem Cell Treatment Center, along with sister affiliates, the Miami Stem Cell Treatment Center and the Manhattan Regenerative Medicine Medical Group, abide by investigational protocols using adult adipose derived stem cells (ADSCs) which can be deployed to improve patients quality of life for a number of chronic, degenerative and inflammatory conditions and diseases. ADSCs are taken from the patients own adipose (fat) tissue (found within a cellular mixture called stromal vascular fraction (SVF)). ADSCs are exceptionally abundant in adipose tissue. The adipose tissue is obtained from the patient during a 15 minute mini-liposuction performed under local anesthesia in the doctors office. SVF is a protein-rich solution containing mononuclear cell lines (predominantly adult autologous mesenchymal stem cells), macrophage cells, endothelial cells, red blood cells, and important Growth Factors that facilitate the stem cell process and promote their activity.
ADSCs are the body's natural healing cells - they are recruited by chemical signals emitted by damaged tissues to repair and regenerate the bodys injured cells. The Irvine Stem Cell Treatment Center only uses Adult Autologous Stem Cells from a persons own fat No embryonic stem cells are used. Current areas of study include: Emphysema, COPD, Asthma, Heart Failure, Parkinsons Disease, Stroke, Multiple Sclerosis, Lupus, Rheumatoid Arthritis, Crohns Disease, and degenerative orthopedic joint conditions. For more information, or if someone thinks they may be a candidate for one of the adult stem cell protocols offered by the Irvine Stem Cell Treatment Center, they may contact Dr. Gionis directly at (949) 679-3889, or see a complete list of the Centers study areas at: http://www.IrvineStemCellsUSA.com.
About the Irvine Stem Cell Treatment Center: The Irvine Stem Cell Treatment Center, along with sister affiliates, the Miami Stem Cell Treatment Center and the Manhattan Regenerative Medicine Medical Group, is an affiliate of the Cell Surgical Network (CSN); we are located in Irvine and Westlake, California. We provide care for people suffering from diseases that may be alleviated by access to adult stem cell based regenerative treatment. We utilize a fat transfer surgical technology to isolate and implant the patients own stem cells from a small quantity of fat harvested by a mini-liposuction on the same day. The investigational protocols utilized by the Irvine Stem Cell Treatment Center have been reviewed and approved by an IRB (Institutional Review Board) which is registered with the U.S. Department of Health, Office of Human Research Protection; and the study is registered with Clinicaltrials.gov, a service of the U.S. National Institutes of Health (NIH).

The Irvine Stem Cell Treatment Center Announces Adult Stem Cell Public Seminars in Orange County, California
Some people say that osteoarthritis, cartilage degradation, and chronic joint pains degenerative diseases associated with agingare conditions with no cure, but Dr. Charlie Poblete and Dr. Jae Pak say otherwise.
It is a new era of medicine, opens Dr. Jae Pak, one of Koreas premier orthopedic stem cell surgeons and a visiting expert consultant of the Stem Care Orthopedics Department under Aivee Institute (AI). He was recently in the country to shed light on stem cell therapy and how it offers more accessible treament options for patients suffering from degenerative orthopedic conditions.
Dr. Pak was joined by Dr. Charlie Poblete, one of the countrys leading orthopedic surgeon who has a special interest on regenerative medicine and stem cells. Incidentally, Dr. Poblete is the head of the Stem Care Orthopedic Department of AI. Stem cells are not really part of alternative medicine. Its part of a modern medicine because we are talking about the biochemistry that goes on in the body with stem cell treatment, Dr. Charlie relates while adding, the good thing about medicine nowadays is its starting to look at the molecular aspect of the body, the molecular and cellular side of medicine.
Over the years, stem cell therapy has been touted as one procedure that can heal multitude of bone, cartilage, and joint ailments. Stem cells are the bodys natural healing cells. They are recruited by chemical signals emitted by damaged tissues to repair and regenerate the damaged cells. Stem cells derived from an individuals tissues may well be the next major development in medicine. In the right environment, these stem cells can change into bone, cartilage, muscle, fat, collagen, neural tissue, blood vessels, and even some organs. Stem cells may also effect healing by secreting special chemical messengers that repair damaged tissue.
There are many clinical conditions that benefits from stem cell therapy: heart attack patients have shown quicker healing period, improved condition for patients with multiple sclerosis, muscular dystrophy, Parkinsons disease, ALS, and stroke. Stem cells may also be effective in the treatment of macular degeneration, Crohns disease, and numerous pulmonary conditions. Also, stem cells are now used for patients with kidney failure and in the treatment of critical limb ischemia.
Stem Cell therapy is a simple procedure. Fat is aspirated from the tummy or the thighs, and then we separate the stem cells from them. It is then activated and injected into joints to restore and regenerate, explains Dr. Jae.
Stem Care by The Aivee Group is the countrys pioneer in advanced Autologous Stem Cell Therapy with an esteemed orthopedic team of doctors and surgeons regarded with international qualifications. The institute, with its CEO and medical director Dr. Z. Teo, together with his wife dermatologist Dr. Aivee Teo, now features a stronger multifaceted protocol in treating orthopedic ailments with a faster rate of positive patient response. They are also adept in complimentary therapies to further intensify the restorative powers of stem cells through the effective use of Growth Factors, Shockwave, Radio Frequency, and Electro Magnetic Therapies. 4033245, 4031982, 09209665613, 09175210222. http://www.stemcareinstitute.com

Mayo Clinic's Dr. Shane Shapiro Discussing Latest in Stem Cell Research at #WSCS14 - Video
Turning 10 years old may not quite mark adolescence for a human child, but for a major government research effort such as California's stem cell program, it's well past middle age.
So it's a little strange to hear C. Randal Mills, the new president and chief executive of the program known formally as the California Institute for Regenerative Medicine, say it's time to instill in CIRM "a clear sense of mission."
But that's what Mills is planning for the coming year, as he launches CIRM 2.0, a comprehensive reboot of the program.
Mills, a former biotech company chief executive, took over as CIRM's president last May. His first task, he told me, was to "take a step back and look broadly at how we do our business." He reached the conclusion that "there was a lot of room for improvement."
That's a striking admission for a program that already has allocated roughly two-thirds of its original $3-billion endowment.
Biomedical researchers are sure to find a lot to like about CIRM 2.0, especially Mills' commitment to streamline the program's grant and loan approval process for projects aimed at clinical trials of potential therapies. Reviews of applications take about 22 months on average; Mills hopes to cut that to about three months. The process can be made more efficient without sacrificing science: "We need to do it quickly and also focus on quality," he says in a videotaped presentation on the CIRM website. The CIRM board last month approved a six-month, $50-million round of funding under the new system, all to be aimed at testing new therapies.
Yet the focus on drug development shows that CIRM remains a prisoner of the politics that brought it into existence. The Proposition 71 campaign in 2004 employed inflated promises of cures for Parkinson's disease, Alzheimer's, diabetes and other therapy-resistant conditions to goad California voters into approving the $3-billion bond issue ($6 billion with interest) for stem cell research.
CIRM says it has funded clinical trials of 10 therapies and has backed an additional 87 projects "in the later stages of moving toward clinical trials." In scientific terms that's progress, but it may fall short of the public expectations of "cures" stoked by the initiative's promoters 10 years ago.
And that poses a political problem. At its current rate of grant and loan approvals of about $190 million a year, CIRM has enough funding to last until 2020. What happens after that is an open question, but any campaign to seek new public funding may depend on CIRM's having a successful therapy to show off to voters.
Mills says winning approval for more public funding isn't the goal of CIRM 2.0. "It's not our job at CIRM to extend the life of CIRM," he told me. Instead, he couches the need for urgency in terms of serving patients. As chief executive of Maryland-based Osiris Therapeutics, where he worked before joining CIRM, he says, he had "a firsthand view into the significance of stem cell treatment, and of how important urgency is in this game." Osiris received approval from the Food and Drug Administration and Canadian regulators for a stem cell drug to treat children with severe complications from bone marrow and other blood transplants.

Two-thirds of all adult cancer cases are primarily the result of bad luck, according to the authors of a new study appearing in Fridays edition of the journal Science.
Dr. Bert Vogelstein, the Clayton Professor of Oncology at the Johns Hopkins University School of Medicine, and Dr. Cristian Tomasetti, an assistant professor of oncology at the Johns Hopkins University School of Medicine and Bloomberg School of Public Health, developed a statistical model that measured the proportion of cancer incidence across many different tissue types.
They found that two-thirds of adult cancer incidence across tissues occur when the random mutations that take place during stem cell division drive cancer through, while the remaining one-third of cases are the result of environmental factors and inherited genes.
All cancers are caused by a combination of bad luck, the environment and heredity, and weve created a model that may help quantify how much of these three factors contribute to cancer development, explained Dr. Vogelstein, who is also co-director of the Ludwig Center at Johns Hopkins and an investigator at the Howard Hughes Medical Institute.
Cancer-free longevity in people exposed to cancer-causing agents, such as tobacco, is often attributed to their good genes, but the truth is that most of them simply had good luck, he said, adding that that poor lifestyle choices can also contribute to this so-called bad luck factor.
The authors said that the implications of their model could alter the public perception about cancer risk factors, as well as impact the funding of research related to the disease.
If most cancer cases can be explained by random DNA mutations that occur as stem cells divide, explained Dr. Tomasetti, it means that lifestyle changes will be a tremendous help when it comes to preventing some forms of the disease, but will be less effective against other types.
As a result, the medical community should should focus more resources on finding ways to detect such cancers at early, curable stages, he added. He and Vogelstein said that they reached their conclusion by searching scientific literature for data on the cumulative number of total stem cell divisions among 31 tissue types that take place during a persons lifetime.
Stem cells renew themselves, repopulating cells that die off in specific organs, the researchers said. Cancer arises when tissue-specific stem cells experience mutations in which one chemical letter in DNA is erroneously swapped for another during the replication process.

WEDNESDAY, Dec. 31, 2014 (HealthDay News) -- Using stem cells derived from a patient's own bone marrow, researchers have repaired a fistula -- a potentially fatal tissue abnormality -- in the man's lower airway.
"This is another interesting new therapeutic approach for stem cells," said lead researcher Dr. Francesco Petrella, deputy director of thoracic surgery at the European Institute of Oncology in Milan, Italy.
The patient, a 42-year-old firefighter, developed the fistula after surgeons removed a lung as part of treatment for mesothelioma cancer. A fistula is abnormal tissue connecting an organ, blood vessel or intestine to another structure. In this case, the fistula developed between the lower airway and the tissue that surrounds the lungs.
"Our clinical experience supports the idea that stem cells could be effectively used to close some tissue defects developing after very complex surgical procedures, thus restoring a functioning airway," Petrella said.
A fistula that develops after chest surgery is serious and even deadly, Petrella said. Current treatments involve removing ribs and taking medications for months or years, he explained.
"Less invasive approaches like endoscopic glue injections have only poor results, so our proposed techniques could improve quality of life in these patients," Petrella said.
Sixty days after stem cell therapy, the firefighter's fistula was healed, the researchers said. The hole seen before stem cell therapy was no longer visible, having been replaced by new tissue created by the stem cell implant, they explained.
Some people are born with a fistula. Other causes of fistulas include complications from surgery, injury, infection and diseases, such as Crohn's disease or ulcerative colitis.
Petrella believes that this same stem cell technique could be used to treat fistulas that develop elsewhere in the body.
