Fig 2. The effects of mushroom extracts and compounds on neurite outgrowth of differentiating N2a cells by using (a) quantification of neurite bearing cells, and (b) chromogenic method at optical density 562.

NGF (50 ng/mL) was used as a positive control. Values are mean ± SD from three independent experiments. Different alphabets represent significant differences between samples (p < 0.05).
