Question

Quizplus · Accepted Answer

BrDU is commonly used to label dividing cells. The dentate gyrus is part of the hippocampus and is known to have a high rate of neurogenesis, the generation of new neurons. The subgranular zone is the location of the neural stem cells that give rise to new neurons in the dentate gyrus. Therefore, the BrDU-stained neurons likely originated from the subgranular zone.
