PDX, CDX and Allograft Growth in the R2G2® Mouse

Three recent studies made it clear: the R2G2® mouse is well suited for preclinical cancer studies that generate PDX, CDX and allograft models. The R2G2® mouse exhibited reduced radiosensitivity compared to NSGTM mice and tolerated estrogen supplementation and three standard-of-care chemotherapy drugs reasonably well. Moreover, as compared to other traditionally used immunodeficient strains, the R2G2® mouse had higher take rates and more favorable tumor growth.
