Figure Lengend Snippet: A. Immunocytochemistry (ICC) analysis demonstrates strong B7-H3 (CD276) expression on both PC-3 cancer cells and pCAFs, visualized by red fluorescence. B. In 2D co-culture assays, anti-B7-H3 CAR T cells exhibit antigen-specific cytotoxicity against PC-3 cells, with killing efficiency increasing across graded effector-to-target (E:T) ratios.

Article Snippet: Primary human anti–B7-H3 antibody (AF1027, R&D Systems) was diluted in cold staining buffer (0.5 μg/μL; 2 μL per 100 μL reaction volume) and applied to cells for 20–30 min at 4 °C.

Techniques: Immunocytochemistry, Expressing, Fluorescence, Co-Culture Assay
