Figure 4

Transmission electron microscopy showing the presence of specific nephron cell types within the kidney organoids generated from human-induced pluripotent stem cells. A diagram of the presumed location of specific cell types along the nephron is shown centrally. (a) Distal tubular epithelium showing clear lumen and small apical microvilli (b, ) Proximal epithelial tubules showing evidence (bʹ) of brush border (bb) and cell–cell tight junctions (tj) (c, ) Forming glomerulus with evidence of tightly interdigitated podocytes (cʹ) with primary (fpf) and secondary (sfp) foot processes.
