Representative confocal images of control and PIK3CAE542K vascular networks. Vascular networks were labeled with fibrin (magenta), 4′,6-diamidino-2-phenylindole (DAPI) (white), actin (green), and endothelial cell–specific CD31 staining (cyan). Vascular networks were fixed 3 days after seeding. Scale bars, 100 μm.
