Human pericytes support formation of microvascular structures. (a) HUVECs seeded onto Matrigel-coated wells formed typical capillary-like structures after 24 hours (scale bar = 1 mm). (b) Human muscle pericytes formed morphologically similar network structures within 6–8 hours (scale bar = 1 mm). (c) Cocultured dye-labeled HUVECs (red) and pericytes (green) at 1 : 1 ratio on Matrigel showed coformation of capillary-like networks within 6–8 hours (scale bars = 500 μm).
