Effects of AnSC-exos on TGF-β1-induced FMT in vitro. A Schematic diagram of the experimental design. B Immunofluorescence staining of α-SMA. C Number of α-SMA⁺ cells. D, E Western blot protein bands of α-SMA and their relative intensities. Note: AnSC-exos reduced the expression level of α-SMA, and this effect was more potent than that of bMSC-exos. Mean ± SEM; **P < 0.01, ****P < 0.0001; n = 3. hDFs, human dermal fibroblasts
