ADSC-Exos promote the proliferation, migration, and tenogenic differentiation of TSCs. a, b Effect of different concentrations of ADSC-Exos on the proliferation of TSCs by EdU assays. c–f Effect of different concentrations of ADSC-Exos on the migration of TSCs by transwell assays and scratch assays. g–l Western blot analysis of protein levels of TNMD, collagen I, SCXA, ALP, and Runx2 induced by different concentrations of ADSC-Exos. Bars, 100 μm.
