Fig. 7.

(a, b) SEM micrographs and (c, d) fluorescent images of BMSCs cultured on CM-0, CM-10, CM-20, CM-30, CM-40, CM-50 and a control group with no microspheres for 4 and 7 days. (e) Proliferation of BMSCs on microspheres after 1, 4, 7 and 11 days. Yellow arrows indicate the microsphere. Error bars represent standard deviation from the mean (n = 3) (***p < 0.001; **p < 0.01; *p < 0.05).
