TCR-T cells, i.e. T-cell receptor-engineered T cells, are constructed to enable T cells to specifically kill the tumor cells by inserting the TCR chains that can specifically recognize the tumor antigen into T cells through gene engineering. Hillgene is specialized in provision of integrated CDMO solutions for cellular therapy products, has established a completely closed process development platform for cellular therapy products, and therefore, can provide high-quality CDMO services for cells to clients with various demands.
