Phil Reyes, one of the Parkinson's patients in Summit 4 Stem Cell, urges California's stem cell agency to support its research.

A potentially groundbreaking trial to treat spinal cord injuries with tissue grown from human embryonic stem cells will resume, after being funded by the California's stem cell agency.

The California Institute for Regenerative Medicine's governing committee approved without opposition a $14.3 million award to Asterias Biotherapeutics of Menlo Park. Asterias is taking over from Geron, which stopped clinical trials in November, 2011. Geron, also of Menlo Park, said it discontinued the trials for business reasons. Asterias is a subsidiary of Alameda-based BioTime.

Patients will be given transplants of neural tissue grown from the embryonic stem cells. The hope is that the cells will repair the severed connections, restoring movement and sensation below the injury site.

CIRM also unanimously approved a $5.6 million grant for another potential breakthrough: a clinical trial by Sangamo Biosciences of Richmond, Calif, to cure HIV infection with gene therapy. The trial is now in Phase II. Immune cells are taken from the patient and given a mutant form of a gene that HIV uses to get inside the cells. The mutated gene resists infection. The genetically altered cells are then given back to the patient.

Approval of both grants had been expected, as staff reports had recommended their approval. The agency met in San Diego.

In addition CIRM's Independent Citizens Oversight Committee funded $16.2 million in grants to bring three stem cell researchers to California. That vote was more contentious, with some committee members arguing that it made no sense to bring more scientists to California without a specific need. In addition, they argued that CIRM's main emphasis needs to be on funding clinical trials.

Member Jeff Sheehy said that bringing the scientists to California doesn't create more scientific capacity. However, a vote to deny funding failed, and a subsequent vote to approve funding passed.

CIRM is projected to run out of its $3 billion in bond funding by 2017, and supporters of the public agency are considering asking California voters for more money.

Also appearing at the CIRM meeting were advocates of funding a stem cell-based therapy for Parkinson's disease. The therapy, which may be approved in 2015 for a clinical trial, uses artificial embryonic stem cells called induced pluripotent stem cells grown from the patient's own skin cells. The group, Summit 4 Stem Cell, plans to ask for funding to help with the trial in the near future.

Ranking among the X-Men probably isn't all that it's cracked up to be, but who wouldn't want their uncanny ability to regenerate lost bone or tissue? New research into tooth repair and stem cell biology, from a cross-institution team led by David Mooney of Harvard's Wyss Institute, may bring such regeneration one step closer to reality or at the very least, give us hope that we can throw away those nasty dentures.

The researchers employed a low-power laser to trigger human dental stem cells to form dentin, a hard bone-like tissue that is one of four major components of teeth (the others being enamel, pulp, and cementum). This kind of low-level light therapy has previously been used to remove or stimulate hair growth and to rejuvenate skin cells, but the mechanisms were not well understood, results varied, and evidence of its efficacy was largely anecdotal.

The new work is the first to document the molecular mechanism involved, thus laying the foundations for controlled treatment protocols in not only restorative dentistry but also avenues like bone regeneration and wound healing. "The scientific community is actively exploring a host of approaches to using stem cells for tissue regeneration efforts," said Wyss Institute Founding Director Don Ingber. "Dave [Mooney] and his team have added an innovative, noninvasive, and remarkably simple but powerful tool to the toolbox."

To test the team's hypothesis, Praveen Arany, an assistant clinical investigator at the National Institutes of Health, drilled holes in the molars of rats and mice, then treated them with low-dose lasers and temporary caps. Around 12 weeks later, tests confirmed that the laser treatments triggered enhanced dentin formation.

Further experiments were conducted on microbial cultures in the laboratory, where they found that a regulatory cell protein called transforming growth factor beta-1 (TGF-1) was activated in a chemical domino effect that in turn caused the stem cells to form dentin. The good news there is that TGF-1 is more or less ubiquitous, with key roles in many biological processes such as immune response, wound healing, development, and malignancies.

This means we could one day see the technique used to do far more than help repair teeth. But first it needs to clear planned human clinical trials, so for now you'll have to make do with dentures, canes and all manner of other prosthetics while the likes of Wolverine prance around with self-healing bodies.

A paper on the research was recently published in the journal Science Translational Medicine.

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.
