Distribution of GMG Cells in the Normal Uterus

Abstract

In rats and mice GMG cells appear in, and form a significant population of, the decidua basalis in the week or so which follows implantation and it is only later that they are present in large numbers in the mesometrial triangle and form the metrial gland. There is also a progression in the disappearance of GMG cells, first from the decidua basalis and later from the metrial gland, so that at parturition in both species only occasional GMG cells are found. Although there are similarities in the distribution of GMG cells in these two species the details of their distribution are described in separate sections.
