Researcher Receives New Faculty Award for Stem Cell Research from The California Institute for Regenerative Medicine (12/21/2007)

The latest round of grants for stem cell research has been approved for funding by the 29-member Independent Citizens Oversight Committee (ICOC), governing board of the California Institute for Regenerative Medicine (CIRM). The New Faculty Award to David Traver, assistant professor of biological sciences at the UC-San Diego, will fund his research into how the stem cells of the blood-forming system are generated, providing $2,803,375 over five years. ...> Full Article

Reprogrammed adult cells treat sickle-cell anemia in mice (12/11/2007)

Mice with a human sickle-cell anemia disease trait have been treated successfully in a process that begins by directly reprogramming their own cells to an embryonic-stem-cell-like state, without the use of eggs. This is the first proof-of-principle of therapeutic application in mice of directly reprogrammed "induced pluripotent stem" (IPS) cells, which recently have been derived in mice as well as humans. ...> Full Article

Adult stem cells lack key regulator (10/24/2007)

The protein Oct4 plays a major role in embryonic stem cells, acting as a master regulator of the genes that keep the cells in an undifferentiated state. Unsurprisingly, researchers studying adult stem cells have long suspected that Oct4 also is critical in allowing these cells to remain undifferentiated. Indeed, more than 50 studies have reported finding Oct4 activity in adult stem cells. ...> Full Article

Neighborly care keeps stem cells young (10/11/2007)

Researchers show that in older flies a steep decline in the growth factor unpaired (upd), which is necessary to maintain stem cells, results in fewer stem cells in the testis of the fruit fly Drosophila. Identifying the reasons for reduced upd expression could reveal how aging leads to changes in stem cell behavior, and counteracting these changes may slow the loss of adult stem cells during aging. ...> Full Article
