The effects of aqueous and ethanolic extracts of P. giganteus on neurite outgrowth of PC12 cells. (a) & (b) Time- and dose-dependent neurite outgrowth induced by aqueous extract and ethanolic extract, respectively. * p < 0.05 compared with positive control NGF and negative control. (c) & (d) Percentage of neurite-bearing cells on day 3 for aqueous extract and ethanolic extract, respectively. Results shown represent the mean ± SD; n = 5. Means not sharing a common letter were significantly different at p < 0.05.
