hBMSC-EXOs improve cell viability and proliferation in chondrocytes. Rabbit primary chondrocytes were treated with hBMSC-EXOs at different dosages as indicated. 24 h or 48 h posttreatment, cell proliferation and cell viability were examined. (a) Cell viability was increased by hBMSC-EXOs in chondrocytes. CCK-8 assay was used to analyze cell viability. n = 3. (b) Cell proliferation was enhanced by hBMSC-EXOs in chondrocytes. Cell proliferation was assayed by EdU incorporation. n = 3. Scale bar = 400 μm. (c) Quantitative analysis for EdU incorporation as shown in (b). Values are presented as mean ± SEM. ns means no significance. ∗P < 0.05 and ∗∗∗P < 0.001, versus the control group, one-way ANOVA.
