The proliferation of MSCs from different sources was detected by CCK-8 assays. The proliferative capacity of B-BM-MSCs was greater than that of BM-MSCs, as the cell proliferation rates on day 4 were 110.94% ± 17.02% and 79.95% ± 11.21%, respectively, (p < 0.05). n = 6. *p < 0.05, **p < 0.01, ***p < 0.001
