Adult Stem Cells Might Restore Hearing
A report from Marine Biological Laboratory found that adult stem cells show promise for restoring inner ear hair cells (see 08/09/2004 headline). The tests, done on mice, might lead to treatment of hearing loss and balance disorders that affect 28 million Americans.
A few days earlier, Jonathan Knight, in Nature, worried over the possibility that cloning hype will undermine research on embryonic stem cells.
While adult stem cells continue to rack up successes, can anyone point to a clear case of embryonic stem cells doing any good? If a promising technology without ethical concerns trumps a questionable one with huge ethical concerns, why is there a contest?
