11. A xenograft model is a graft of tissue transplanted between organisms of different species. 12. Azacitidine induces tumor regression on isocitrate dehydrogenase-1 mutant glioma xenografts in mice. 13. This was very successful in downregulating the proliferation of renal carcinoma cells in xenografts . 14. An immune response against an allograft or xenograft is termed graft-versus-host disease. 15. A biomaterial may also be an autograft, allograft or xenograft used as an organ transplant material. 16. Furthermore, researchers have found that it successfully reduces the growth of xenograft tumors in rat models. 17. Xenografts from other species and man-made artificial hearts are two less successful alternatives to allografts.18. In 1892, Robert Weir experimented unsuccessfully with xenografts ( duck sternum ) in the reconstruction of sunken noses. 19.
