Caption: In a study that demonstrates a close connection between the development of brain cells and blood vessels, blood vessels (green) grow normally in a developing mouse brain on left. On right, blood vessels (red) have collapsed in mice with a defective gene in glial cells, which support the growth of the neurons that carry nerve signals. The research, by Zhen Huang, a neuroscientist at the University of Wisconsin–Madison, shows how developing neural cells control the growth of blood vessels.
