In vitro angiogenesis potential. A Representative fluorescence images of HUVECs after coculture for 3 and 6 h. B Quantification of total length, branch points, number of junctions, and number of meshes in HUVECs. C qRT-PCR analysis of angiogenesis-related gene expressions including CD31, ANG, vWF, and VEGF-A. Statistically significant differences are indicated with *p < 0.05, **p < 0.01, ***p < 0.001, ****p < 0.0001
