Fig. 7: Exosomal miR-197-3p promotes angiogenesis and migration via silencing TIMP2/3 in HUVECs.

A The protein levels of TIMP3, VEGFR2, ERK and p-ERK in different HUVECs were determined by western blot. B The protein levels of TIMP2, MMP2 and MT1-MMP in different HUVECs were determined by western blot. C Angiogenesis was assessed by tube formation assay with quantitative analysis (right panel). D, E Cell migration was assessed by wound healing and transwell assays with quantitative analysis (right panel). Data were representative images or were expressed as the mean ± SD of n = 3 experiments. **P < 0.01, ***P < 0.001.
