Gene Found to Switch Off Stem Cells During Aging
The finding indicates that many of the degenerative diseases of aging are caused by an active shutting down of the stem cells that renew the body’s various tissues, and are not just a passive disintegration of tissues under life’s daily wear and tear, as is often assumed.
“I don’t think aging is a random process – it’s a program, an anti-cancer program,” said Dr. Norman E. Sharpless of the University of North Carolina, senior author of one of the three reports. The two other senior authors are Dr. Sean J. Morrison of the University of Michigan and Dr. David T. Scadden of the Harvard Medical School.
