Gene expression analysis of ADMSCs, EMSCs and BMMSCs. Bar chart representing the transcript level of (Collagen Type II, Aggrecan, and TGF-b1) in different groups at 4 weeks post treatment. values are presented as mean ± SEM (n = 3 rabbits/group). Data were calculated by 2− ∆∆CT method, using (actin-β) as internal control, and then normalized to the control negative value which was set to be 1. The control negative is healthy and normal tissue; thus all our target genes are downregulated in other groups because they all suffered from auricular injury. We performed one-way ANOVA to analyze our data. Different superscript letters indicate significant differences between each other P < 0.05
