Vascularisation of engineered kidney rudiments on chick chorioallantoic membrane (CAM). a The CAM itself. b Chick vessels entering an engineered kidney rudiment (the dark object, centre). c A section through such a kidney: present are S-shaped body-stage (SB) nephrons and more mature nephrons that have Bowman’s capsules with glomeruli (G) and a lower cleft (LC) consisting of podocytes (Po) and endothelial cells (En). As in normal nephrons, the distal tubule (DT) approaches the glomerular entrance, where it makes a macula densa (MD)
