We performed two co-cultured CRISPR screens in the ovarian cancer cell line OVCAR-8, using two distinct CAR-THP-1 cell lines: liquid tumor relevant CD19-targeting CAR-THP-1 (Supplementary Fig. 1A-B), and solid tumor relevant EphA2-targeting CAR-THP-1 (Supplementary Fig. 1C-D). The gene discussed is CD19; the disease is ovarian carcinoma.
