Figure 5.
Gene expression measured by real-time quantitative polymerase chain reaction after incubation for 3 days (A), 7 days (B), and 14 days (C).
Notes: a–dP<0.05 versus mono siCkip-1, siFlt-1, and siNC transfection or blank sponge, respectively.
Abbreviations: ALP, alkaline phosphatase; OCN, osteocalcin; VEGF, vascular endothelial growth factor; siNC, negative control small interfering RNA; siCkip-1, small interfering RNA targets casein kinase 2 interaction protein 1; siFlt-1, small interfering RNA targets soluble VEGF receptor 1.
