Fig. 4From: A novel targeted angiogenesis technique using VEGF conjugated magnetic nanoparticles and in-vitro endothelial barrier crossingShows disposition of the magnetic nanoparticles with VEGF and HUVECs in matrigel at 0 and 24 h. Panels a to d demonstrate the confocal images of 4 experiments in Matrigel observing the disposition of Magnetic Nanoparticles with VEGF on the left side of each panel and HUVEC cells on the right side. Panels a to d, each has upper and lower panels which correspond to immediate (0 hr), and at 24 hr after the experimental setupBack to article page
