Transplantation into Genetically Alymphoid Mice as an Approach to Dissect the Roles of Uterine Natural Killer Cells during Pregnancy— A Review

Mice genetically deficient in the natural killer (NK) cell lineage lack uterine (uNK cells) and demonstrate morphometrically-quantifiable histopathology within their implantation sites. Two particular mouse strains, tg(epsilon),26 and RAG-2 null x gamma(c) null, have been used successfully as transplant recipients to address questions relating to the biology of uNK cells. uNK cells did not differentiate within decidualized uterine graft …
