We have examined the role of microtubules and microfilaments in neurite outgrowth by chemically modifying their interaction in Neuro-2a neuroblastoma cells. Cells exposed to taxol (1 microM), an agent that promotes microtubule polymerization and stabilization, did not form neurites over a 24 h period. Similarly, cells exposed to cytochalasin D (4 microM), an agent which promotes microfilament depolymerization, did not develop neurites. However, cells treated simultaneously with taxol (1 microM) and cytochalasin D (4 microM) produced long (50 microns) thin, unbranched neurites. Neurites formed during this simultaneous treatment grew in a circular pattern, lacked typical growth cones, were packed densely with microtubules and were deficient in microfilaments. Untreated cells maintained in control medium for 24 h formed short (15 microns), thick, highly branched neurites containing a dense meshwork of microtubules, microfilaments and neurofilaments. These results demonstrate that taxol does not block neurite outgrowth from Neuro-2a cells maintained under microfilament-limiting conditions. They suggest further that microtubules may provide the major cytoskeletal framework for neurite elongation.
