Fig. 1: Concentration-dependent of CEE on the proliferation of CMSCs.

a Morphological images of CMSCs in each group. Scale bars, 200 μm. b Proliferation rate of CMSCs according to the variations in the concentration of CEE at 72 h (n = 5). Values are presented as the mean ± SE. a-f Different letters represent statistically significant differences among treatment groups (p < 0.01).
