Effects of aqueous extracts on the neuritogenic activity of PC-12 cells. The percentage of neurite-bearing cells of PC-12 cells treated with various concentrations of aqueous extracts ranged from 25 to 100 μg/ml. Cells in complete F-12 K medium without treatment served as a negative control. Cells treated with 50 ng/ml of NGF or 50 μg/ml of H. erinaceus (HE) served as positive controls. Data were expressed as means ± standard deviation (n = 3). Means with different alphabets shows significant difference p < 0.05. *** p < 0.001 compared to NGF.
