Endodermal and gut tissues from 9SS to 27SS, were enzymatically dissociated using 0.25% trypsin (Gibco, 25200-056) for roughly 4 minutes at 37°C. The reaction was halted by the addition of 0.4 volumes of fetal bovine serum (FBS). The resultant cell suspension was centrifuged at 1000 rpm for 5 minutes at 4°C, followed by supernatant removal. To prepare single-cell suspensions from endodermal and gut samples, cells were incubated with anti-EpCAM-APC antibody (Invitrogen, 17-5791-82, dilution 1:100) in FACS buffer (comprising HBSS buffer with 1% FBS) for 20 minutes at 4°C in darkness. Following incubation, cells were washed with FACS buffer and subjected to analysis and sorting using BD FACSAriaTM Fusion flow cytometers. Dead cells were excluded from the analysis through staining with 1 µg/mL DAPI (Macklin, D807022). For 10x Genomics scRNA-seq, libraries were constructed using the Single Cell 3′ Reagent Kit v3.0 instructions from 10x Genomics, following manufacturer's protocols.
