Neurotrophic activity assay of MPC and MSC conditioned media using cultured DRGs. (A) Neurite density was imaged using ×4 interference microscopy after culture for 3 days with growth medium or neurotrophic induction media that had been conditioned with factors secreted by MPCs or MSCs; scale bar = 250 µm. (B) The number of neurites that extended beyond the average neurite length in control DRG medium (1.75 mm) as a result of culture with growth medium or neurotrophic induction medium conditioned by MPCs or MSCs; a,bp < 0.05, b,cp < 0.05, a,cp < 0.01, one-way ANOVA with SNK post hoc comparisons and n = 4
