mRNA expression in UCMSCs differentiated with MDI (open circle), MDI-I (black square), and MDI-R (gray triangle) for 0–5 weeks was analyzed via quantitative RT-PCR (n = 6 per treatment group). A: PPARγ, B: C/EBPα, C: FABP4, D: GPD1, E: PLIN1, F: PLIN2, G: LEP, H: ADIPOQ. Values are expressed as mean fold change from undifferentiated UCMSCs (0 week) ± SE. The Y-axis is log-scale. Repeated measures two-way ANOVA followed by Tukey’s multiple comparison test was performed to compare treatment groups. For each time point, * represents a significant difference from MDI, † represents a significant difference between MDI-I and MDI-R, ‡ represents a significant difference between MDI and MDI-R, and § represents a significant difference between MDI and MDI-I (P < 0.05).
