The latent stem cell population is retained in the hippocampus of transgenic Huntington's disease mice but not wild-type mice.

The demonstration of the brain's ability to initiate repair in response to disease or injury has sparked considerable interest in therapeutic strategies to stimulate adult neurogenesis. In this study we examined the effect of a progressive neurodegenerative condition on neural precursor activit...
