The development of adult-born neurons in the dentate gyrus over time
Photomicrographs show the gradual development of adult-born granule cells (green) from 7 to 30 days of age in coronal brain sections derived from a sedentary young adult male C57Bl/6 mouse. Dividing cells in the dentate gyrus were labeled with retrovirus-expressing green fluorescent protein (GFP) and imaged 7, 14, or 30 days later. Nuclei were stained with 4',6-diamidino-2-phenylindole (DAPI), blue.
