Figure 4

Effect of NGF or NGF(1-14) peptides on neuronal phenotype differentiation. (A–F): Photomicrographs obtained by microscopy of PC12 cells treated with 50 ng/mL NGF or 50 μM NGF(1-14) peptides for 72 h. Representative photos obtained from at least three independent experiments for: (A) unstimulated control, (B) NGF(1-14), (C) d-NGF(1-15), (D) s-NGF(1-14), (E) NGF(14-1), (F) NGF. Scale bar = 50 μm. (G): Percentage of neurite total length of PC12 cells treated with 50 ng/mL NGF or 50 μM NGF(1-14) peptides for 72 h, (* p < 0.05 versus control, one-way Anova).
