a Bioluminescence standard curve of iPSC-EC cell number, representative cell bioluminescence images (inset). b iPSC-EC growth at 3 and 7 days on electrospun scaffolds of varying flow rate and PCL/gelatin blends. ***p < 0.001, **p < 0.01 compared to PCL (8 ml/h) control scaffolds within the same time point. n = 5 scaffolds/group. c CD31 quantification of iPSC-EC cultures on scaffolds at 7 days in vitro. *p < 0.05, **p < 0.01. n = 5 scaffolds/group. d Representative photographs of iPSC-EC cultures stained with CD31 (red) and counterstained with DAPI (blue) at 5×; magnified images at 10× (inset). Scale bar represents 100 μm, inset scale bar represents 10 μm. iPSC-EC induced pluripotent stem cell-derived endothelial cell, PCL polycaprolactone, PG73 PCL/gelatin (70:30 ratio), PG55 PCL/gelatin (50:50 ratio), DAPI 4',6-diamidino-2-phenylindole
