The impact of cAD-MSC-derived exosome treatment on fibroblast gene expression in vitro. mRNA expression of (A) wound healing-related markers, including Tgfβ1, Tgfβ3, Col3a1, TNFα, and (B) glucose utilization marker Glut1, was observed using qRT-PCR after 24 h of treatment. The mean and p-value are denoted. (C) Pearson’s correlation analysis across different gene marker expressions related to the effect of cAD-MSC-derived exosome treatment on fibroblast in vitro. The asterisks illustrate the significant levels compared to the control (*p < 0.05, **p < 0.01, ***p < 0.001).
