Figure 3.

Effects of cyclic tensile stretch on osteogenic differentiation marker genes of ASCs. ALP (A) and OCN (B) gene expression are shown in different mechanical loading duration (6 h continuous loading and 17 min every day for consecutive 1 d, 3 d, 7 d, and 10 d). Bars represent mean ± SEM; n = 3; Significant differences among the groups are noted by *p < 0.05
