Fig. 10 mr?NPNT enhances vessel formation in hydrogels. A, Examples of projections of confocal images of HUVECs (passage number 2, P2) cultured in collagen?I?based hydrogels stained for endothelial specific marker CD31 and DNA by 4?,6?diamidino?2?phenylindole. Yellow dots: examples of junctions. Green asterisks: examples of meshes. B, Schematic of a vascular network indicating measured parameters. C, Quantitative analysis of (A) (n=3) regarding vasculature complexity based on branching index, number of meshes, and total length (segments + branches). Statistical significance was determined by a 2?tailed Student's t test. Data are meanąSEM. ***P?0.001. DAPI indicates 4?,6?diamidino?2?phenylindole; HUVEC, human umbilical vascular endothelial cell; mr?NPNT, recombinant mouse nephronectin.
