Comparison of the percentage of neurite-bearing cells with different specific inhibitors treatment. (a) U0126 (10 μM), (b) PD98059 (40 μM), and (c) LY294002 (30 μM). NGF, 25 μg/ml of aqueous extract (denoted simply by 25), and negative control were the control groups i.e. without the treatment with inhibitors. Results shown represent the mean ± SD; n = 3. * Significant difference at p < 0.05 versus control group.
