PC12 pheochromocytoma cells treated with nerve growth factor (NGF) for two weeks in spinner cultures quickly begin to form processes after plating on an appropriate substrate, while cells freshly exposed to NGF in monolayer culture initiate neurite outgrowth only after a lag period of several days. The present ultrastructural studies indicate that PC 12 cells treated with NGF in spinner cultures do not form neurites, but do form short extensions comparable to those which have been reported within the first two days of exposure to NGF in monolayer cultures. These extensions contain organelles believed to be required for locomotion and for transport of cytoskeletal and membrane components and neurotransmitters. They also form bulbous distensions in which numerous chromaffin-type granules accumulate. These findings suggest that NGF may affect cells in spinner cultures by promoting development or activation of axonal transport mechanisms, and that the existence of these mechanisms may contribute to the neurite outgrowth which the cells exhibit when plated. NGF-treated PC 12 cells in spinner cultures do not accumulate the agranular synaptic-like vesicles, which are typically found in comparably treated monolayer cultures and which have been hypothesized to be sites of acetylcholine storage. These and other data demonstrate that attachment to a substrate can selectively modulate the responses of PC 12 cells to NGF.
