Ghrelin regulated AKT phosphorylation and apoptotic signaling pathways. ((a)–(c)) Western blot and quantification of phosphorylation of AKT (normalized to total AKT), Bcl-2, and Bax respectively (all normalized to control group). (d) Ghrelin increased VEGF secretion in ADMSCs after H/SD injury; * P < 0.05 versus control group, # P < 0.05 versus H/SD group, and $ P < 0.05 versus ghrelin (10−8 M) group.
