Generation of NOD-scid Il2rg−/− extended pluripotent stem cells. (A) Schematic of two approaches used for generating NOD-scid Il2rg−/− extended pluripotent stem cells: de novo derivation from blastocysts (upper panels) and chemical reprogramming from embryonic fibroblasts (lower panels). (B) Phase-contrast images of de novo derived outgrowth and EPS colonies for 17 passages in LCDM medium. Scale bars, 100 μm. (C) qRT-PCR analysis of XEN marker genes expression during the chemical induction process (day 16). Error bars indicate SEM (n = 2). (D) Co-immunostaining of XEN marker genes during the chemical induction process (day 16). Upper panels: GATA6 and SALL4; lower panels: SOX17 and SALL4. Scale bars, 100 μm. (E) Immunofluorescence of OCT4-positive primary colonies at the end of the chemical induction (day 40). Scale bars, 100 μm. (F) Typical karyotypes of EPS (passage 22) and cEPS (passage 23) cells. Each cell line counts 30 cells
