A. MN9D cells treated with C3 transferase (2.5 μg/ml for 48h) show extension of neurites (top: phase contrast; bottom: immunostained with an antibody against β-III tubulin (Tuj-1). Bar = 40 μm. B. Quantitative analysis of the number of processes per cell, the mean length of processes per cell in μm, the maximum length of processes from individual cells in μm, and the number of branches per neuritic process.
