From: PTH (1-34) enhances the therapeutic effect of bone marrow mesenchymal stem cell-derived exosomes by inhibiting proinflammatory cytokines expression on OA chondrocyte repair in vitro

Fig. 3

The effect of ExoBMSC and ExoPTH on OA chondrocyte proliferation was assayed by immunofluorescence staining for ki67 and PCNA. A Immunofluorescence staining for ki67 and PCNA. B The positive expression ratio of ki67. C The positive expression ratio of PCNA. Data are presented as the mean ± SD, *p < 0.05 versus OA group and #p < 0.05 versus ExoBMSC group. Bars = 50 μm. Ctrl, control; OA, osteoarthritis; ExoBMSC, exosomes derived from BMSCs; ExoPTH, exosomes derived from PTH-preconditioned BMSCs; BMSCs, bone marrow mesenchymal stem cells
