Biotin-E-FABP increases neurite outgrowth and neurite length of nerve growth factor-differentiated pheochromocytoma cells (NGFDPC12). (a) Quantitative analysis of percent differentiation. For biotin-E-FABP groups, the percent differentiation was determined only among biotin-E-FABP-containing cells (green-staining cells). (b) Quantitative analysis of average neurite length. Again, only greenstaining cells were included for biotin-E-FABP groups. Error bars represent the SEM of three experiments. Statistical significance between groups was determined by two-way anova. *p < 0.01; **p < 0.05. E-FABP, epidermal fatty acid-binding protein.
