Changes in expression of growth factor and stemness genes under the different culture conditions. (A) Relative expression levels of two growth factor genes in ADMSCs from the four different conditions. (B) Relative expression levels of stemness genes in ADMSCs from the four different conditions. Expression of β-actin served as the internal control. The gene expression ratios were normalized to the corresponding levels measured for cells cultured under the Im condition. Each bar represents the mean value ± SD (n = 3). * P < 0.05. ** P < 0.01. *** P < 0.005.
