DHEA boosts growth rate of human neural stem cells - 2/2/2004
|
Human neural stem cells, exposed in a lab dish to the steroid DHEA,
exhibit a remarkable uptick in growth rates, suggesting that the
hormone may play a role in helping the brain produce new cells,
according to a new study published this week in the online editions of
the Proceedings of the National Academy of Sciences (PNAS).
The new work, conducted by a team of scientists at the University of
Wisconsin-Madison, provides some of the first direct evidence of the
biological effects of DHEA on the human nervous system, according to
Clive Svendsen, the study's senior author and an authority on brain
stem cells at UW-Madison's Waisman Center.
