In vitro angiogenesis study of Cu-DCA NZs. (A) Images of HUVECs migration with different treatments for 0, 12, and 24 h. (B) Images of HUVECs migration with different treatments in transwell migration assay. (C) Images of tube formation with different treatments. (D) Western blot analysis of VEGF expression levels. GAPDH served as an internal reference. (E) The HUVECs migration ratio with different treatments. (F) Number of cells passing through the membrane in the transwell migration assay. (G) Total length of the tube network in tube formation assay. Data are presented as the mean ± SD (n = 3). * p < 0.05, ** p < 0.01, and *** p < 0.001
