摘要
The objectives of this study were to show the effect of miR-222 expression on angiogenesis and the mechanism of angiogenesis differentiation of bone microvascular endothelial cells. For the study, the concentration of VEGF release was detected by ELISA, and cell activity was shown using a CCK-8 (Cell Counting Kit-8). We used western blotting to detect VEGFR, TGF- β , and bFGF expression. The results showed that miR-222 expression by day 14 was significantly lower compared to the expression results for days 3 and 7. Additionally, miR-222 expression on day 7 was significantly lower than on day 3. MiR-222 expression in the control group and PELA group decreased gradually over time. On day 14, miR-222 expression in the VEGF microcapsule scaffold group was at its lowest level. Our conclusions were that the regulation of the angiogenesis of bone microvascular endothelial cells appears to be related to (1) the effect of miR-222 on VEGFR and TGF- β , and (2) how bFGF expression is regulated.
