Assessment of angiogenesis using HUVECs (A, B) and iPSC-derived ECs (C, D) on both Geltrex™ (A, C) and SP-105 hydrogel (B, D) extracellular matrices treated with angiogenic inhibitors. Concentration–response plots for ECs treated with suramin (red), SU5402 (blue), nocodazole (orange), and TAB (green). Concentration–response graphs shown were prepared in GraphPad using a normalized nonlinear fit. Data points in each concentration–response plot represent the average ± SEM of three separate experiments. SEM, standard error of the mean; TAB, tetraoctylammonium bromide.
