Probing the power of stem cells

Piece by missing piece, scientists at the Keck School of Medicine of USC are deciphering the powerful gene regulatory circuit that maintains and controls the potential of embryonic stem cells (ESCs) to form any type of cell in the body.

Recent findings by Provost Professor Andrew McMahon, director of the Eli and Edythe Broad Center for Regenerative Medicine and Stem Cell Research at USC, and Qilong Ying, associate professor of cell and neurobiology, underscore the essential role of basic science in paving the way for future medical breakthroughs.

McMahon and Ying are in pursuit of the ways in which the intricate

Stanford’s Irving Weissman on the (lost?) promise of stem cells

Stanford stem cell researcher Irving Weissman, MD, published an article in Cell Stem Cell today discussing barriers to stem cell research:

While I am usually an optimist, I must admit that there is a possibility that we will continue to be in the Dark Ages of medicine for quite some time. I fear that therapies using purified tissue and organ-specific stem cells – the only self-renewing cells in a tissue or that can regenerate that tissue or organ for life – will remain elusive.

Weissman, who directs Stanford’s Institute for Stem Cell Biology and Regenerative Medicine, goes on to cover the

Regenerative Medicine Generates Hope

With the motto Advancing Science to Heal the World the BU stem cell scientists who founded the Center for Regenerative Medicine(CReM) could be pegged as starry-eyed idealists or scientific superheroes. Or perhaps a bit of both.

CReM codirectors Darrell Kotton, Gustavo Mostoslavsky, and George Murphy have established themselves as venturesome researchers who are willing to share their discoveries with almost anyone. And they do it for free—bucking the prevailing trend to patent, publish, and protect scientific breakthroughs. The trio’s “open source biology” is just one of the things they teach to the next generation of stem cell researchers at CReM.

Adult stem cell: blind can now see

Dozens of people who were blinded or otherwise suffered severe eye damage when they were splashed with caustic chemicals had their sight restored with transplants of their own stem cells — a stunning success for the burgeoning cell-therapy field, Italian researchers reported Wednesday.

The treatment worked completely in 82 of 107 eyes and partially in 14 others, with benefits lasting up to a decade so far. One man whose eyes were severely damaged more than 60 years ago now has near-normal vision.

“This is a roaring success,” said ophthalmologist Dr. Ivan Schwab of the University of California, Davis, who

New stem cell therapy could be used to halt Huntington’s advance

A team of researchers at the UC Davis Institute for Regenerative Cures has developed a technique for using stem cells to deliver therapy that specifically targets the genetic abnormality found in Huntington’s disease, a hereditary brain disorder that causes progressive uncontrolled movements, dementia and death. The findings, now available online in the journal Molecular and Cellular Neuroscience, suggest a promising approach that might block the disease from advancing.

“For the first time, we have been able to successfully deliver inhibitory RNA sequences from stem cells directly into neurons, significantly decreasing the synthesis of the abnormal huntingtin protein,” said Jan A.
