Uniaxial Static Strain Promotes Osteoblast Proliferation and Bone Matrix Formation in Distraction Osteogenesis In Vitro

Figure 6

Quantitative gene expression results of (a) PCNA, (b) ALP, (c) Runx2, (d) OCN, (e) collagen type I, (f) HIF-1α, and (g) VEGF for osteoblasts of the 10% uniaxial static strain (USS) group and control group at Day 1, Day 3, and Day 5. Data are presented as fold changes after normalization to GAPDH. Fold changes are shown as for from one experiment; similar trends were observed in three independent experiments. .
