Septal cholinergic neurons from postnatal rat can survive in the dissociate culture conditions in the presence of nerve growth factor.
The survival effect by nerve growth factor (NGF) on the cholinergic neurons of postnatal rat septal neurons in culture was examined. When the septal neurons from 10 to 12-day-old rats were cultured without NGF, the activities of choline acetyltransferase gradually decreased during the period of cultivation. The addition of NGF to the culture prevented the decline of activities. And, the number of acetylcholinesterase-positive neurons in culture with NGF was found to be more than that without NGF, after 5 days in culture. These results suggest that NGF promotes the survival of septal cholinergic neurons from postnatal rats in culture.
