Parent-of-Origin Differences in the Density of Trophoblast Giant Cells in Mouse Hybrid Crosses

Overview

Trophoblast giant cells are found in the placenta and initiate the invasion of the placenta into the uterine lining and provide important hormones for the regulation of the pregnancy. Genomic imprinting is a type of gene expression that, when two different species of mice mate, causes abnormal expression of certain traits depending on the parent-of-origin. We identified the number of trophoblast giant cells in each hybrid and pure cross of mice in their placentas and recorded the data. The results show a relationship between the maternal parent-of-origin and trophoblast giant cell densities. Furthermore, the mother of the cross is directly related to the density of trophoblast giant cells in the placenta. This study will help the scientific community understand more about the significance of trophoblast giant cells in the placenta.
