Stably transfected luciferase‐labeled control (mock) or GLTSCR1‐KO HCT116 cells (Figure S2F, Supporting Information) were injected intravenously into non‐obese diabetes/severe combined immunodeficiency (NOD/SCID) mice, which were then subjected to bioluminescence imaging (BLI). This evidence concerns the gene BICRA and severe combined immunodeficiency.
