Results of tube formation assay of HUVECs. (n = 3) A Representative images of the formed tubules. (scale bars = 100 μm) B The number tube structures per view field of each group. It represents the tubule that has already formed. C The number of master junctions per view field of each group. It represents the potential to form new tubules. D The line graph of the number of meshes E The line graph of the number of master junctions. *p < 0.05, **p < 0.01
