(b) Morphological changes in the neurite outgrowth of PC12 cells treated with negative control (0.5% DMSO) (A), positive control (40 ng/ml NGF) (B), amarogentin (3 μM) (C), NGF (1 ng/ml) (D), and amarogentin (3 μM) with NGF (1 ng/ml) (E). Each experiment was repeated thrice. The data are presented as . indicated significant and highly significant differences compared with the negative control group at .
