Changes in relative protein expression of type I collagen, type III collagen, MMP-1, and MMP-3 mRNA in the dermis. Western blotting showed the relative protein expression of collagen I of SD rats exposed to UVB 28 d after ADSC-derived exosome treatment. Mean ± SD. n = 5. ^∗p < 0.05 vs. UVB(-) group; ^△p < 0.05 vs. UVB(+) group. Western blotting showed the relative protein expression of collagen III of SD rats exposed to UVB 28 d after ADSC-derived exosome treatment. Mean ± SD. n = 5. ^∗p < 0.05 vs. UVB(-) group; ^△p < 0.05 vs. UVB(+) group. Western blotting showed the relative protein expression of MMP-1 of SD rats exposed to UVB 28 d after ADSC-derived exosome treatment. Mean ± SD. n = 5. ^∗p < 0.05 vs. UVB(-) group; ^△p < 0.05 vs. UVB(+) group. Western blotting showed the relative protein expression of MMP-3 of SD rats exposed to UVB 28 d after ADSC-derived exosome treatment.
