Neuroblast

Neuroblast

A neuroblast is a dividing cell that will develop into neurons or glia.[citation needed] The characterisation of neuroblasts and their development in Drosophila melanogaster was widely achieved by Chris Doe, Corey Goodman and Mike Bate. In humans, neuroblasts produced by stem cells in the adult subventricular zone migrate into damaged areas after brain injuries. However, they are restricted to the subtype of small interneuron-like cells, and it is unlikely that they contribute to functional recovery of stratial circuits. [1]

Some sources distinguish neuroblasts from neural stem cells.[2]
