Fig. 5. FGF21 augmentes autophagy in flaps.

Fig. 5

On the 7th day after operation, the samples were harvested for the evaluation of autophagy. a Immunofluorescence for the assessment of LC3II in the ischemic skin flap (scan bar, 15 μm). b Quantification of percentage of positive cells with LC3II labeled autophagosomes in dermal layer. (c) CTSD expression in ischemic skin flap evaluated by IHC. d Histogram showing expression of CTSD detected by IHC. e, f Western blotting for expression of Belin1, LC3II, CTSD, VPS34. and p62, which was corrected by GAPDH as internal control. g Histogram showing the levels of Belin1, LC3II, CTSD, VPS34, and p62 detected by western blotting. Significance: *p < 0.05 and **p < 0.01 vs. the Control group. Data were expressed as means ± SEM (n = 6 per group).
