Embryonic stem cell grafting: the therapy of the future?
The grafting of mouse embryonic haemopoietic cells into deficient recipients is discussed. Donor cells can be obtained from post-implantation mouse embryos in vivo and used to treat X-irradiated or genetically anaemic recipients. The concept of grafting embryonic haemopoietic cells into normal, untreated recipients is also described. Preimplantation mouse blastocysts grown in vitro for 3-4 days can also be used as a source of donor cells. The haematological and immunological aspects of embryonic cell grafting are discussed, followed by a description of current xenotransplantation experiments, including rat into mouse and human into mouse. The review concludes with a discussion of the application of embryonic cell grafting to other tissues and a look into the possible future of this technique.
