title: High oxygen atmosphere for neuronal cell culture with nerve growth factor. I. Primary culture of basal forebrain cholinergic neurons from fetal and postnatal rats.
abstract: Cholinergic neurons cultured from postnatal days 11-13 (P11-P13) rat basal forebrain showed better survival in the culture condition using a 50% O2 atmosphere with and without nerve growth factor (NGF) than in a low (10 or 20%) O2 atmosphere. Except for the culture at a low cell density, the beneficial effect of the highly oxidized culture condition was found in the culture from P3 neurons, but not from embryonic day 18 neurons. The survival of microtubule-associated protein 2 (MAP2)-positive neurons in culture from P3 basal forebrain regions was more enhanced in a 50% O2 atmosphere than in 20% and also 10% O2 atmosphere. The viable number of the MAP2-positive neurons in a 10% O2 condition was about half of that in a 20% condition. These results suggest that the response of the cultured neurons to an incubator O2 concentration changes during the neuronal development in CNS from fetal to postnatal stages.
