title: Granulated metrial gland cells in the pregnant uterus of mice expressing the collagen mutation tight-skin (Tsk/+).
abstract: Influences of the extracellular matrix (ECM) on the differentiation and distribution of granulated metrial gland (GMG) cells, a uterine natural killer (NK)-like cell subset, were studied by histological examination of implantation sites in the mouse mutant Tsk/+. Tsk/+ mice overproduce collagens I and III. GMG cell differentiation appeared to progress normally in Tsk/+ mice between days 6.5 and 12.5 of gestation. The distribution of GMG cells, however, was abnormal. Significant numbers of GMG cells were found in the antimesometrial and lateral decidual regions at day 8.5 of gestation and in the regions between implantation sites until day 10.5 of gestation. Loss of GMG cells from these regions normally occurs by day 6.5 of gestation. These data suggest that alterations to the ECM change the migration properties or life span of GMG cells.
