abstract：:The rat pheochromocytoma cell line PC12 undergoes morphological differentiation into neurone-like cells when exposed to nerve growth factor (NGF). We found that in PC12 cells the enzymatic activity of choline-acetyltransferase and of tyrosine hydroxylase changed very little during NGF exposure, while tyrosine hydroxyl...
