Figure Lengend Snippet: ASC-derived exosomes increased the ratio of TGF-β3 to TGF-β1 in vivo . ( A–D ) Representative images of immunohistochemical staining of TGF-β1, TGF-β3 and CD63 at days 3, 7, 14 and 21 following treatment with 200 µg ASC-Exos or the same volume of PBS orexosome-free conditioned medium (CM-Exo). Scale bar = 100 µm. ( E ) Analysis of the relative density of TGF-β1, TGF-β3 and CD63. Results are presented as mean ± SD; n = 5; *p < 0.05, ** p < 0.01, ***p < 0.001, compared with the control groups.

doi: 10.1038/s41598-017-12919-x

Figure Lengend Snippet: ASC-derived exosomes contributed to regulating ECM reconstruction and reducing scar formation. Exosomes increased the ratio of collagen III to collagen I, reduced myofibroblast differentiation and increased the ratio of TGF-β3 to TGF-β1 in vivo . In addition, exosomes activated the ERK/MAPK pathway in skin dermal fibroblasts and increased the level of MMP3 via activation of the ERK pathway, thereby increasing the ratio of MMP3 to TIMP1 and regulating ECM remodelling.
