HWJMSCs and HWJMSC-EVs promoted the expression of ITGB1 in BMSCs and chondrocytes. A, E, G The viability of treated hWJMSCs, hBMSCs, and chondrocytes was detected by CCK8 assay and observed under light microscopy. Scale bar = 50 µm. Mean ± SD, n = 3. *P < 0.05, **P < 0.01. B–D, F, H The expressions of ITGB1 in cells (hWJMSCs, hBMSCs and chondrocytes) detected by Western blotting. Mean ± SD, n = 3. *P < 0.05, **P < 0.01
