Induction of neurite outgrowth of cultured rat DRG neurons by daidzein and NGF. DRG neuronal cultures were treated for 24 h with (A) DMSO, (B-H) various concentration of daidzein, or (F) NGF (100 ng/ml), then fixed and immunostained for NF-L. A-F, large neurons. G-H, small neurons. Scale Bar = 30 μm.
