Caption: Inside wells about a fifth the size of a dime, a team from the University of Wisconsin–Madison and the Morgridge Institute for Research grew neural tissues from a combination of cell types that represent the main components of a developing brain, including neural progenitor cells, blood vessel cells and brain-specific immune cells called glial cells. This image shows the entire structure formed in the well, with nuclei in blue, neurons in green and glial cells in red.

Caption: This image shows the development of vasculature (in green) around glial cells (red) within a developing neural tissue. The development of vascular networks is a key advance in this initiative, supported by the National Institutes of Health.
