Implantation, deciduoma formation and live births in mast cell-deficient mice (W/Wv).

The intraluminal injection of oil produced deciduoma formation in ovariectomized, mast cell-normal (+/+) and mast cell-deficient (W/Wv) mice that were treated with exogenous steroids. Oil injection and trauma (e.g. sutures) also produced a deciduoma in ovariectomized +/+ and W/Wv mice that had received a single control (+/+) ovary transplanted under the kidney capsule. After transfers of donor blastocysts, implantation and live births were obtained in +/+ and W/Wv mice containing a single ovary transplant. Our results demonstrate that uterine mast cells are not required for the production of a decidual cell response, implantation, gestation or the birth of live offspring in mice.
