2. Figure 1
Different mechanisms and strategies for kidney regeneration. (a) Genetically labeled proximal tubule cells from SLC34a1-CreERt2; R26RtdTomato mouse (red). Lotus tetragonolobus lectin (LTA, green) defines proximal tubule. Merged signal is yellow. (b) During development, inducible enhanced green fluorescent protein-labeled parietal epithelial cells can differentiate into fully equipped podocytes forming foot process interdigitations (green) with resident Tomato-labeled podocytes (red). In addition, interdigitations of parietal podocytes are visible at the vascular pole. Hoechst staining for cell nuclei, × 63 original magnification. (c) Parietal epithelial cells that are responding to retinoic acid and differentiating into podocytes (white arrows) are evidenced by colocalization of immunofluorescence for β-gal (green) and claudin1 (red) in the kidney of RARE-lacZ transgenic mice with adriamycin nephropathy treated with retinoic acid, × 40 original magnification. (d) PAX2+LHX1+ intermediate mesoderm cells differentiated from human pluripotent stem cells. Pax2 is green and Lhx1 is red. Merged signal is yellow. (e) Formation of a self-organizing kidney in culture. Ureteric compartment is visible by phase contrast (left) surrounded by WT1+ mesenchyme (red). (f) A structure reminiscent of a glomerulus and a tubule formed in vitro from single-cell suspension of metanephric mesenchyme. × 20 original magnification.
