Health authorities on Saturday reissued warnings against health facilities and medical practitioners offering stem-cell therapies or related products, which promise to cure a range of diseases, arrest the aging process or even increase libido.

In an advisory, the Food and Drug Administration stressed 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 for general use.

The use of HCT/Ps without the authorization or permission by the FDA is considered illegal, it said. The agency warned 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.

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 healthcare procedures.

If health institutions are doing these three procedures, they can continue because those are allowed, Go said.

But the efficacy of the use of stem cells for the treatment of other diseases, such as diabetes, cancer and autism, among others, have yet to be proven, he said.

Go noted that while many spa centers and salons are advertising stem-cell therapy treatment and products, none of them have secured the FDAs approval. As of now, we have not accredited any health facility offering stem-cell therapy yet.

University of Adelaide researchers have discovered that stem cells taken from teeth can grow to resemble brain cells, suggesting they could one day be used in the brain as a therapy for stroke.

In the Universitys Centre for Stem Cell Research, laboratory studies have shown that stem cells from teeth can develop and form complex networks of brain-like cells. Although these cells havent developed into fully fledged neurons, researchers believe its just a matter of time and the right conditions for it to happen.

Stem cells from teeth have great potential to grow into new brain or nerve cells, and this could potentially assist with treatments of brain disorders, such as stroke, says Dr Kylie Ellis, Commercial Development Manager with the Universitys commercial arm, Adelaide Research & Innovation (ARI).

Dr Ellis conducted this research as part of her Physiology PhD studies at the University, before making the step into commercialization. The results of her work have been published in the journal Stem Cell Research & Therapy.

The reality is, treatment options available to the thousands of stroke patients every year are limited, Dr Ellis says. The primary drug treatment available must be administered within hours of a stroke and many people dont have access within that timeframe, because they often cant seek help for some time after the attack.

Ultimately, we want to be able to use a patients own stem cells for tailor-made brain therapy that doesnt have the host rejection issues commonly associated with cell-based therapies. Another advantage is that dental pulp stem cell therapy may provide a treatment option available months or even years after the stroke has occurred, she says.

Dr Ellis and her colleagues, Professors Simon Koblar, David OCarroll and Stan Gronthos, have been working on a laboratory-based model for actual treatment in humans. As part of this research Dr Ellis found that stem cells derived from teeth developed into cells that closely resembled neurons.

Stem Cells Taken From Teeth Can Make Brain-like Cells

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.
