a Quantification of total VEGF expression at the wound site. *p < 0.05, **p < 0.01, ***p < 0.001, ****p < 0.0001. n = 5 samples/group. b Quantification of VEGF expression location in surrounding tissue vs within the scaffold. *p < 0.05 comparing VEGF expression within the surrounding tissue only, #p < 0.05 comparing VEGF expression within scaffolds only. n = 5 samples/group. c Representative photographs of VEGF staining with DAPI counterstain, scale bar represents 100 μm. Tissue implant interface marked by dotted lines: above represents tissue, below represents scaffold. VEGF vascular endothelial growth factor, iPSC-EC induced pluripotent stem cell-derived endothelial cell, PG73 polycaprolactone/gelatin (70:30 ratio), DAPI 4',6-diamidino-2-phenylindole
