CARTmeso-CXCL9 cells enhanced tumor eradication in a xenograft model. a Schematic diagram of the experimental process. H322 cells expressing luciferase were inoculated into NOD/SCID mice subcutaneously. On day 3, mice were treated with PBS, UTD, CARTmeso and CARTmeso-CXCL9 cells. b, c The bioluminescence image was recorded weekly to monitor tumor growth. d The survival curves of mice were analyzed. N = 5 mice/group, *p < 0.05 (the log-rank test)
