A Tubular formation on Matrigel and digital analysis conversion of HUVECs in different treatments, bar = 100 μm. (B, C) Total length and the number of nodes were quantified. D CLSM images of the expression analysis of CD31, bar = 25 μm. E The expression level of CD31 and VEGF protein. F Quantification analysis of the CD31 and VEGF protein. *P < 0.05, **P < 0.01, ***P < 0.001Back to article page
