In vitro cell experiments. a: Cell viability of BMSCs co-cultured with extracts of MOC, 1.25 wt% PA-MOC, and 1 wt% SrR/1.25 wt% PA-MOC; b: ALP activity of BMSCs co-cultured with extracts of MOC, 1.25 wt% PA-MOC and 1 wt% SrR/1.25 wt% PA-MOC (There are significant differences, *p < 0.05); c: Live/Dead staining of BMSCs co-cultured with extracts of MOC, 1.25 wt% PA-MOC and 1 wt% SrR/1.25 wt% PA-MOC for 1 d and 3 d
