Immunoglobulin G in the decidua basalis and metrial gland of the pregnant mouse uterus.

The distribution of immunoglobulin G (IgG) in the decidua basalis and metrial gland of the mouse uterus at days 10 and 14 of pregnancy has been investigated using immunohistochemical methods. IgG was found in the intercellular spaces but none was found in decidual cells, stromal cells of the metrial gland or granulated metrial gland cells. These results differ from those of other studies which have localised IgG in the cytoplasm of rat granulated metrial gland cells.
