Abstract
Chimeric antigen receptors (CARs) are provided. When the CARs herein are expressed on the surface of immune cells, such immune cells may be directed to osteosarcoma cells. In a murine intraperitoneal model, the tumor growth was significantly delayed for T cells expressing a CAR comprising a scFv from TP1 or TP3 antibodies. Immune cells expressing the CARs herein display therapeutic effect in the form of decreased tumor volume in a murine model simulating metastatic osteosarcoma. Combined with the finding that stem cells from healthy bone marrow were not significantly affected by T cells expressing any of the CARs, the CARs may be used for the treatment of osteosarcoma.
