Establishment of PDO and ODX models of OICI-EPS-0530. (A) The scheme of the establishment of PDO and ODX. (B) The morphology of OICI-EPS-0530 organoids under ALI organoid culture by phase-contrast microscopy. (C) Growing organoid images of OICI-EPS-0530 at day 1, day 4 and day 8. Scale bars: 100μm. (D) Relative organoids viability from 0 h to 72 h. (n = 6; *P < 0.05). (E) Developed tumors in NSG mice of ODX-1 (n=1) and ODX-2 (n=3) from PDO of OICI-EPS-0530. (F) RT-PCR with the primer set in INI1-CD1 and INI1-CD2. No band was present for the negative control (N.C.) of distilled water. Hela and Kamui-EWS (Ewing sarcoma cell line established in our institute) were demonstrated for positive control.
