Expression of B7 costimulation molecules by colorectal cancer cells reducestumorigenicity and induces anti-tumor immunity

Figure 6 Cytotoxicity of abdominal cavity infiltrating lymphocytes (ACIL) against tumor cells. A: Cytotoxicity of CMT93-B7 induced ACIL against CMT93-B7 tumor cells, n = 4. B: Cytotoxicity of CMT93-B7 induced ACIL against CMT93 wild type tumor cells, n = 4. C: Cytotoxicity of CMT93 induced ACIL against CMT93 wild type tumor cells, n = 4. By paired Student's t test: A is different from B significantly, P < 0.05; B is different from C significantly, P < 0.05.
