Blocking c-Fos expression also blocks neuritogenesis. Cells cultured with NGF or NGF + SO or NGF + ASO for 4 d (A) or subjected to different temporal additions or withdrawals of NGF or ASO or NLSP as indicated at left (B and C) were immunostained for c-Fos (left) and α-Tub (right). Morphometric quantification data obtained as in Fig. 1 are posted to the right of the corresponding row. Bar, 10 μm. ^*, significantly shorter that cells treated 4 d with NGF at p < 0.00001 (by ANOVA test as in Figure 1).
