Human Embryonic Stem Cell Marker Panel (Hicks et al., 2020 (link); Roth et al., 2020 (link); Bomba et al., 2021 (link); Osnato et al., 2021 (link)) (Abcam, ab238602) was used to analyze pluripotency protein markers by immunofluorescence. A Trilineage Differentiation Kit (Ward et al., 2017 (link)) (STEMCELL, #05230) was used to induce differentiation into the three germ layers. Human three Germ Layer 3-Color Immunocytochemistry Kit (Han et al., 2020 (link)) (R&D, SC022) was used to identify specific protein markers of the three germ layers. A Giemsa Stain solution (Solarbio, G1015) was used to analyze the karyotype. Fluorescence images were obtained under an LSM900 laser scanning confocal microscope (Zeiss, Germany).
