BEIRUT: Fat removal and a non-surgical facelift at the same time might sound like a two-for-one offer too good to be true. But that is a pretty common combination at the Innovi Stem Cell Therapy Clinic, where doctors extract stem cells from the bodys fat to do any number of cosmetic cleanups, from scar removal to diminishing fine lines and wrinkles.

The clinic opened five months ago in the Beirut neighborhood of Sodeco, bringing Lebanon its first specialized center in stem cell research.

Around the world at any given medical conference, from fields as diverse as orthopedics to dentistry, stem cells have become one of the main events, as researchers believe these undifferentiated cells hold the cure to some of the gravest human diseases: cancer, diabetes, multiple sclerosis, to name a few.

In a country like Lebanon, stem cell specialists figured the best way to support their research was to offer one of the most in-demand medical procedures: cosmetic surgery.

Walking through the halls of the elegant, albeit quaint, clinic, one will see top-of-the-line fat freezing technology, equipment for laser hair removal and facilities where doctors carry out medical face peels and stretch mark treatment.

They also offer Ozone therapy, which uses pure oxygen that can supposedly alleviate a range of maladies from skin disorders and premature aging to chronic pain.

But we are not a beauty clinic, said one of the doctors, who asked not to be identified due to Lebanons strict medical advertising laws.

These cosmetic procedures complement their work in stem cells, a far less understood and rapidly evolving area of medicine. Innovi, for example, has built the Middle Easts only stem cell bank, where up to 19,000 vials can be frozen and preserved with liquid nitrogen. The closet housing the bank, which looks like an enormous washing machine, now holds the stem cells of a modest 10 clients.

The clinic has become a hub for various stem cells research. Doctors have visited from Europe and a Syrian doctor is now working with a couple to try and grow sperm from the stem cells of a man with aspermia.

But cosmetic treatments and stem cells go well together as doctors have been using fat-derived cells, also called adipose stem cells, as a Botox-like filler for almost a decade.

Mice have been poked, prodded, injected and dissected in the name of science. But there are limits to what mice can teach us especially when it comes to stem cell therapies. For the first time, researchers haveturned skin cells into bone in a creature more closely related to humans: monkeys.

In a study published Thursday in the journal Cell Reports, scientists report that they regrew bone in 25rhesus macaques using induced pluripotent stem cells (iPSCs) taken from the creatures skin. Since macaques are more closely related to humans, their discovery could help push stem cell therapies into early clinical trials in humans.

While this is the good news, the bad news is that iPSCs can also seed tumors in monkeys; however, the tumors grew at a far slower rate than in previous studies in mice. This finding further emphasizes the key role primates likely will play in testing the safety of potential stem cell therapies.

Repairing Bone

Researchers used a common procedure to reprogram macaque skin cells, and coaxed them into pluripotent cells that were capable of building bone. They seeded these cells into ceramic scaffolds, which are already used by surgeons used to reconstruct bone. The cells took, and the monkeys successfully grew new bone.

In some experiments, the monkeys formed teratomas nasty tumors that can contain teeth and hair when they were injected with undifferentiated iPSCs, or cells that have the potential to change into any kind of cell. However, the tumors grew 20 times slower than in mice, highlighting an important difference between mice and monkeys.

Fortunately, tumors did not form in monkeys that were injected with differentiated iPSCs, or cells that were programmed to createbone cells.

Advancing Research

Researchers say their successful procedure proves that monkeys willplay an important rolein research on therapies using iPSCs. These monkeys will help scientists test and analyze risks associated with the therapies and improve their safety.

Researchers have shown for the first time in an animal that is more closely related to humans that it is possible to make new bone from stem-cell-like induced pluripotent stem cells (iPSCs) made from an individual animal's own skin cells. The study in monkeys reported in the Cell Press journal Cell Reports on May 15th also shows that there is some risk that those iPSCs could seed tumors, but that unfortunate outcome appears to be less likely than studies in immune-compromised mice would suggest.

"We have been able to design an animal model for testing of pluripotent stem cell therapies using the rhesus macaque, a small monkey that is readily available and has been validated as being closely related physiologically to humans," said Cynthia Dunbar of the National Heart, Lung, and Blood Institute. "We have used this model to demonstrate that tumor formation of a type called a 'teratoma' from undifferentiated autologous iPSCs does occur; however, tumor formation is very slow and requires large numbers of iPSCs given under very hospitable conditions. We have also shown that new bone can be produced from autologous iPSCs, as a model for their possible clinical application."

Autologous refers to the fact that the iPSCs capable of producing any tissue typein this case bonewere derived from the very individual that later received them. That means that use of these cells in tissue repair would not require long-term or possibly toxic immune suppression drugs to prevent rejection.

The researchers first used a standard recipe to reprogram skin cells taken from rhesus macaques. They then coaxed those cells to form first pluripotent stem cells and then cells that have the potential to act more specifically as bone progenitors. Those progenitor cells were then seeded onto ceramic scaffolds that are already in use by reconstructive surgeons attempting to fill in or rebuild bone. And, it worked; the monkeys grew new bone.

Importantly, the researchers report that no teratoma structures developed in monkeys that had received the bone "stem cells." In other experiments, undifferentiated iPSCs did form teratomas in a dose-dependent manner.

The researchers say that therapies based on this approach could be particularly beneficial for people with large congenital bone defects or other traumatic injuries. Although bone replacement is an unlikely "first in human" use for stem cell therapies given that the condition it treats is not life threatening, the findings in a primate are an essential step on the path toward regenerative clinical medicine.

"A large animal preclinical model for the development of pluripotent or other high-risk/high-reward generative cell therapies is absolutely required to address issues of tissue integration or homing, risk of tumor formation, and immunogenicity," Dunbar said. "The testing of human-derived cells in vitro or in profoundly immunodeficient mice simply cannot model these crucial preclinical safety and efficiency issues."

LOS ANGELES (EMBARGOED UNTIL NOON ET ON MAY 6, 2014) Investigators at the Cedars-Sinai Heart Institute whose previous research showed that cardiac stem cell therapy reduces scarring and regenerates healthy tissue after a heart attack in humans have identified components of those stem cells responsible for the beneficial effects.

In a series of laboratory and lab animal studies, Heart Institute researchers found that exosomes, tiny membrane-enclosed "bubbles" involved in cell-to-cell communication, convey messages that reduce cell death, promote growth of new heart muscle cells and encourage the development of healthy blood vessels.

"Exosomes were first described in the mid-1980s, but we only now are beginning to appreciate their potential as therapeutic agents. We have found that exosomes and the cargo they contain are crucial mediators of stem cell-based heart regeneration, and we believe this might lead to an even more refined therapy using the 'active ingredient' instead of the entire stem cell," said Eduardo Marbn, MD, PhD, director of the Cedars-Sinai Heart Institute and a pioneer in developing investigational cardiac stem cell treatments.

"The concept of exosome therapy is interesting because it could potentially shift our strategy from living-cell transplantation to the use of a non-living agent," he added. "Stem cells must be carefully preserved to keep them alive and functioning until the time of transplant, and there are some risks involved in cell transplantation. In contrast, exosome therapy may be safer and simpler and based on a product with a longer shelf life."

In lab experiments, the researchers isolated exosomes from specialized human cardiac stem cells and found that exosomes alone had the same beneficial effects as stem cells. Exosomes also produced the same post-heart attack benefits in mice, decreasing scar size, increasing healthy heart tissue and reducing levels of chemicals that lead to inflammation. Even when exosomes were injected in mice after heart attack scars were well-established, and traditionally viewed as "irreversible," they brought about multiple structural and functional benefits.

Exosomes transport small pieces of genetic material, called microRNAs, that enable cells to communicate with neighboring cells to change their behavior. The researchers pinpointed one such microRNA one that is especially plentiful in cardiac stem cell exosomes as responsible for some of the benefits. It is likely, they believe, that this and other microRNAs in the exosomes work together to produce the regenerative effects.

"The exosomes appear to contain the signaling information needed to regenerate healthy heart tissue, they are naturally able to permeate cells, and they have a coating that protects their payloads from degradation as they shuttle from cell to cell," said Marbn, senior author of an article in the May 6, 2014 Stem Cell Reports. "Injecting exosomes derived from specialized cardiac stem cells may be an attractive alternative to the transplantation of living cells."

MANILA, Philippines Health authorities warned the public anew on Saturday about health facilities and medical practitioners offering unauthorized stem cell therapy and products.

In an advisory, the Food and Drug Administration said that to date, not one stem cell or human cells, tissues, and cellular and tissue-based products (HCT/Ps) that applied for registration has been registered by the FDA for compassionate or clinical trial use, or general use.

The use of HCT/Ps without the authorization or permission by the FDA is considered illegal, it said, reminding hospitals and health facilities of the provisions of the FDA Act of 2009, which prohibits the manufacture, use, advertisement or sponsorship of unregistered health products.

This warning extends to all unlicensed practitioners from other countries and to tourists who visit the Philippines for leisure and medical needs, the advisory added.

According to FDA acting director general Kenneth Hartigan Go, the FDA recognizes only hematopoietic (pertaining to the formation and development of blood cells) stem cell transplantation, corneal resurfacing with limbal stem cells and skin regeneration with epidermal stem cells as generally accepted standards of health care procedures.

If health institutions are doing these three procedures, they can continue doing them because those are allowed. Go said, adding that the efficacy of the use of stem cells for the treatment of other diseases, such as diabetes, cancer and autism, among others, has yet to be proven.

Go noted that while many spa centers and salons are advertising stem cell therapy and products, none of them has the approval of the health agency.

As of now we have not accredited any health facility offering stem cell therapy yet, Go said.

Several facilities had applied for accreditation but Go said many of these were asked to correct their deficiencies.

A number of factors such as the increasing funding from various government and private organizations, growing industry focus on stem cell research, and increasing global awareness about stem cell therapies through various organizations are stimulating the research activities for stem cell therapies. Developing markets, emergence of induced pluripotent stem (iPS) cells as an alternative to embryonic stem cells (ESCs), and evolution of new stem cell therapies represent high growth opportunities for market players.

In 2015, North America will hold the largest share of the global stem cell therapy market. This large share is primarily attributed to the extensive government funding and increasing fast-track approval for stem cell therapeutics by the FDA. Moreover, development of advanced genomic methods for stem cell analysis and high number of ongoing research activities are further fueling the growth of the stem cell therapy market in North America. However, the Asia-Pacific stem cell therapy market is expected to grow at the highest CAGR in the forecast period, owing to factors such as increasing regulatory support through favorable government policies, strong product pipelines, and increasing licensing activities in this region.

Stem Cell Therapy Market (Autologous & Allogeneic) Worth $330 Million in 2020 - New Report by MarketsandMarkets

Heart cells created from human embryonic stem cells successfully restored damaged heart muscles in monkeys.

The results of the experiment appear in the April 30 advanced online edition of the journal Nature in a paper titled, "Human embryonic-stem cell derived cardiomyocytes regenerate non-human primate hearts."

The findings suggest that the approach should be feasible in humans, the researchers said.

"Before this study, it was not known if it is possible to produce sufficient numbers of these cells and successfully use them to remuscularize damaged hearts in a large animal whose heart size and physiology is similar to that of the human heart," said Dr. Charles Murry, UW professor of pathology and bioengineering, who led the research team that conducted the experiment.

A physician/scientist, Murry directs the UW Center for Cardiovascular Biology and is a UW Medicine pathologist.

Murry said he expected the approach could be ready for clinical trials in humans within four years.

In the study, Murry, along with Dr. Michael Laflamme and other colleagues at the UW Institute for Stem Cell & Regenerative Medicine, experimentally induced controlled myocardial infarctions, a form of heart attack, in anesthetized pigtail macaques.

The infarcts were created by blocking the coronary artery of macaque for 90 minutes, an established model for the study of myocardial infarction in primates.

In humans, myocardial infarctions are typically caused by coronary artery disease. The resulting lack of adequate blood flow can damage heart muscle and other tissues by depriving them of oxygen. Because the infarcted heart muscle does not grow back, myocardial infarction leaves the heart less able to pump blood and often leads to heart failure, a leading cause of cardiovascular death.

The goal of stem cell therapy is to replace the damaged tissue with new heart cells and restore the failing heart to normal function.

New research looking at the success of clinical trials of stem cell therapy shows that trials appear to be more successful in studies where there are more discrepancies in the trial data.

Researchers from Imperial College London conducted a meta-analysis of 49 randomised controlled trials of bone marrow stem cell therapy for heart disease. The study, published today in the British Medical Journal, identified and listed over 600 discrepancies within the trial reports.

Discrepancies were defined as two (or more) reported facts that could not both be accurate because they were logically or mathematically incompatible. For example, one trial reported that it involved 70 patients, who were divided into two groups of 35 and 80.

The researchers found eight trials that each contained over 20 discrepancies.

The researchers found that the discrepancy count in a trial was the most important determinant of the improvement in cardiac function reported by that trial. Trials with fewer and fewer discrepancies showed progressively smaller improvements in cardiac function. The five trials with no discrepancies at all showed an effect size of zero (see bar chart in Notes to Editors).

Previous meta-analyses looking at the results of lots of clinical trials have suggested that on average, bone marrow stem cell therapy has a significant positive effect on improving heart function. However, some trials have shown that it successfully improves heart function whilst others have not. The reasons for this are unclear.

Professor Darrel Francis, one of the study authors from the National Heart and Lung Institute at Imperial College London, said: "Clinical trials involve a huge amount of data and so it is understandable that discrepancies sometimes arise when researchers are presenting their findings. However, our study suggests that these discrepancies can have a significant impact on the overall results. It is a powerful reminder to all of us conducting clinical trials to be careful and vigilant to avoid discrepancies appearing in the work.

Putnam Valley, NY. (Apr. 23, 2014) People who have had a stroke, often suffer motor deficits with little potential to restore neurological function. However, a study conducted in Taiwan, that will be published in a future issue of Cell Transplantation, but is currently freely available on-line as an unedited early e-pub at: http://www.ingentaconnect.com/content/cog/ct/pre-prints/content-ct1168Chen, has found that when one group of stroke victims had their own peripheral blood stem cells (PBSCs) injected directly into the brain and a similar group did not, those who received the PBSCs experienced some "improvement in stroke scales and functional outcome." Those in the PBSC-injected group also received injections of the growth factor granulocyte-colony stimulating factor (G-CSF), known to be potentially neuroprotective.

"In this phase 2 study, we provide the first evidence that intracerebral injection of autologous (self-donated) PBSCs can improve motor function in those who have suffered a stroke and have motor deficits as a result," said study corresponding Dr. Woei-Cheng Shyu of the Center for Neuropsychiatry, Graduate Institute of Immunology and Translational Medicine Research Center, China Medical University in Taiwan. "Our study demonstrated that this therapeutic strategy was feasible and safe in stroke patients who suffered a prior stroke, but within five years from the onset of symptoms."

According to the authors, there has been little advance made in restoring neurological function following ischemic stroke. However, since neuronal death is the primary mechanism that limits functional recovery, stem cell therapy is emerging as a potentially effective regenerative approach. Once more PBSCs are being increasingly used as a self-donated source for cell therapies for regenerating skeletal muscle, heart and neurons. The PBSCs may need to be "amplified" with G-CSF, speculated the researchers.

All of the patients in the trial had suffered a stroke in the past, as long as five years prior to this study. At the end of a 12 month follow-up, the group of 15 patients with neurological deficits who received injections of PBSCs experienced neurological and functional improvement based on a number of clinical outcomes measures. The control group of 15 patients with neurological deficits that did not receive the PBSC injections did not experience the same beneficial outcomes.

The researchers reported that nine of the 15 patients undergoing PBSC transplantation experienced "positive motor evoked potentials" (MEPs) after transcranial magnetic stimulation, but why MEPs appeared in some of the transplanted group, but not all, was unclear.

"Despite this success, it should be noted that this was a preliminary study and, due to the small number of patients, are tentative," concluded the researchers. "In the future we plan to conduct a multi-center, large-scale, double blind, placebo-controlled randomized studies to better evaluate the effect of PBSC implantation in patients suffering from the effects of past stroke."

"This phase II study offers pilot clinical evidence supporting the use of autologous stem cell-based treatment for stroke" said Dr. Cesar V. Borlongan, Prof. of Neurosurgery and Director of the Center of Excellence for Aging & Brain Repair at the University of South Florida. "Clarification of the impact of G-CSF on the cells and whether other factors are necessary to maximize the benefit of cell transplantation, as well as further studies with a larger number of patients are necessary to determine equivocal safety and efficacy of this treatment".
