New support for stem cells as pit crew

Lab-mutated neurodeficient mice were injected with stem cells from 12-day-old mouse brains, resulting in marked improvement. In contrast to beliefs from just a few years ago, the injected cells didn't grow into new brain tissue. Like volunteers spicing up an old folks' home, they stimulated the damaged cells to behave in a more effective fashion.
Another revelation from this study (UC@Irvine) seems to be that the cells congregated in the damaged regions of the mouse brains. We're not sure what made them do it or what made them stay.
