Effects of 600 ng/ml ghrelin on mitogen-activated protein kinase (MAPK) activation in rBMSCs cells. a: The expression of total and phosphorylated ERK1/2, JNKs, and p38 proteins. b: Contrast gray value of phosphorylation of ERK1/2, JNKs, and p38 based on the western blot. Presented as mean ± SD (n = 5). *Significantly different from the 0 min group (P < 0.05)
