Histological analysis. (a) Safranin O and toluidine blue (TB) staining of mesenchymal stem cells (MSCs) that differentiated into chondrocytes in the presence of extracellular vesicles (EVs) derived from chondrocytes (Cho-EV) and MSCs (MSC-EV) after 21 days. (b) Histograms show the intensity of (a) red and (b) purple colors among all groups by safranin O and TB staining, respectively. ; ; and compared to the control group.
