Abstract
Cultures highly enriched in neurons obtained from embryonic mouse cerebra were used to demonstrate that: (1) at the optimum concentration of 10–8M retinoic acid stimulated the neurons to produce axon- and dentrite-like structures as determined by phase contrast and fluorescent microscopy; (2) the same concentration of retinoic acid stimulated acetyl cholinesterase and choline acetyltransferase activities; (3) treatment of neurons of either prenatal or neonatal equivalent age with retinoic acid produced a sustained stimulation of neuronal differentiation, and (4) retinoic acid cooperatively stimulated neuronal differentiation with either thyroid hormone or hydrocortisone.Keywords
