Resveratrol enhanced the expression of brown adipogenic marker genes in differentiated iBAT SVCs after 7-day brown adipogenic differentiation. A) Relative mRNA expression of PRDM16, UCP-1, Cidea and PGC-1a in differentiated iBAT SVCs of wild-type. B) UCP1 immunofluorescence staining of differentiated iBAT SVCs. Nuclei were stained with DAPI (scale bar, 100 µm). C) Western blot analysis of PRDM16UCP1, PDH and Cyto C of differentiated iBAT SVCs. β-actin was used as loading control. D) Mean ± SEM of immunoblotting bands and the intensities of the bands were expressed as arbitrary units. *P < 0.05, **P < 0.01 and *** P < 0.001 versus control.
