Neurons can be successfully generated from passaged neurospheres even after multiple passages. (A) Representative example of neurons from passage 3 after 9 days in vitro immunopositive for the neuronal marker β-tubulin (green) and DAPI labeled cell nuclei (blue). The red arrow indicates a nucleus from a β-tubulin negative cell. (B) Group data for percentage of neurons identified as a function of neurosphere passage number. The percentage was highest in passage 1.
