Fig. 7: Expression of LTL, E-cadherin, and Wt1 in kidney organoids and cell aggregates.

a Whole-mount staining of kidney organoid derived from embryonic stem cell (ESC)-derived renal progenitors shows the presence of LTL+/E-cadherin+ mature proximal tubules. b Embryonic kidney-derived organoids contain only LTL+ immature tubules. c Cell aggregates derived from ESCs do not contain LTL+ tubules. LTL lotus tetragonolobus lectin. Scale bar = 40 µm.
