✦ Synopsis


Pure neuronal cultures prepared from 6-day-old embryonic chick brains incorporated [3H1-thymidine in serum-free medium up to the 4th day in culture. The addition of insulin any time within this culture period caused an increase in thymidine incorporation. This increase in [3Hl-thymidine was correlated with an increase in cell number and percentage of labeling index. Triiodothyronine and endothelial cell growth factor were also active in stimulating [3H]-thymidine incorporation into chick neuroblasts. The effect of these trophic agents is unique since a variety of known mitogens tested were negative.
