Generation of the organotypic kidney by integrating pluripotent stem cell-derived renal stroma

ABSTRACT: Organs consist of not only parenchyma but also stroma, the latter of which coordinates generation of organotypic structures. Despite recent advances in organoid technology, induction of organ-specific stroma and recapitulating the complex organ configurations from pluripotent stem cells (PSCs) has remained challenging. For the kidney, the stromal progenitor coordinates differentiation of the two parenchymal progenitors: nephron progenitor and ureteric bud. By identifying the origin and dorsoventral patterning of the renal stromal progenitor, we established its induction protocol from mouse PSCs. When the three types of progenitors were differentially induced from PSCs and assembled, the all PSC-derived organoids reproduced the complex kidney structures, with multiple types of stromal cells distributed around differentiating nephrons and branching ureteric buds. Thus, integration of PSC-derived stroma into the conventional organoids enables recapitulation of organotypic architecture. Overall design: Kidney mRNA profiles of embryonic day 9.5, E11.5, E15.5, E13.5, E17.5, postnatal day 0 mice and mouse ES cells-derived kidney organoids at single cell resolution.
