Effect of FGF2 priming on H₂O₂-induced DPC death. DPC-S and DPC-FS were exposed to H₂O₂ at various concentrations (0, 0.4, 0.5, and 0.6 mM) for 24 hr, followed by MTT assay. The ratios of the absorbance values for the DPCs exposed to H₂O₂ were calculated relative to the control (H₂O₂-untreated DPCs). The values are expressed as the mean ± SE. Significant differences between the two groups were determined by two-way ANOVA post hoc with Tukey’s multiple comparison test. *p < 0.05, **p < 0.01 vs DPC-S treated with H₂O₂ at the same concentration; ^#p < 0.05, ^###p < 0.001 vs DPC-S untreated with H₂O₂; and ^$$$p < 0.001 vs DPC-FS untreated with H₂O₂, respectively; n = 5.
