Mouse ICM organoids express the PrE markers GATA4 and SOX17. Mouse tet::GATA6 ESCs were stimulated for 6 h with doxycycline (+ dox) to induce PrE differentiation. After the removal of dox, 200 cells formed ICM organoids and were cultured for 24 h or 48 h. (A) GATA4 and SOX17 expression was found on the edge of the ICM organoids 24 h after formation. NANOG expression was found within the ICM organoids. (B) GATA4 and SOX17 expression was maintained 48 h after ICM organoid formation. Microscope: Zeiss LSM880; objective: 40×/1.3 oil differential interference contrast; scale bars, 20 μm. To see this figure in color, go online.
