Article Abstract
Polyploid decidual cells are specifically differentiated cells during mouse uterine decidualization. However, little is known about the regulatory mechanism and physiological significance of polyploidization in pregnancy. Here we report a novel role of E2F8 in the polyploidization of decidual cells in mice. E2F8 is highly expressed in decidual cells and regulated by progesterone through HB-EGF/EGFR/ERK/STAT3 signaling pathway. E2F8 transcriptionally suppresses CDK1, thus triggering the polyploidization of decidual cells. E2F8-mediated polyploidization is a response to stresses which are accompanied by decidualization. Interestingly, polyploidization is not detected during human decidualization with the down-regulation of E2F8, indicating differential expression of E2F8 may lead to the difference of decidual cell polyploidization between mice and humans.

Tracking the translocation of fluorescent-based reporters at the single-cell level in living mouse embryos requires specialized expertise in mouse embryology and deep computational skills. Here, we detail an approach to quantify cyclin-dependent kinase (CDK) activity levels in single cells throughout different stages of the pre-implantation embryo. We discuss in vitro culture strategies that enable efficient live fluorescent confocal image acquisition and subsequent cell tracking.

Purpose: Taenia pisiformis cysticerci have been reported in the female reproductive tract of rabbits, and this parasitosis is known to alter reproductive behavior and reduce embryo implantation; however, tissue-based studies relating the immune system to the implantation site during infection have not been previously addressed. Therefore, our research provides new information on the interaction between pregnancy and parasitic infection.
Methods: This study evaluated the recruitment of immune cells in uterine tissue during T.

Mitochondria in the egg are suggested to be crucial for the onset of new life. However, there is ambiguous knowledge about the necessity for fertilization and early embryonic development. Therefore, we created a conditional Tfam knockout (Tfam; Zp3-Cre) to produce Tfam oocytes for investigation of the mitochondrial abundance in oocytes and early embryos.
