Differences in permissive cytomegalovirus infection between primary cultured human fetal membrane chorion and amnion cells.

چکیده
Human cytomegalovirus (CMV) is the most common cause of viral intrauterine infection in developed countries. It has been shown that CMV DNA was frequently detected in the fetal membranes when the placenta was infected in utero. However, it is still not clear whether CMV replicates in constituent cells of the fetal membranes. We investigated CMV infection of primary cultured chorion and amnion cells prepared from human fetal membrane tissues. In both types of cell cultures, rounded cells were observed at day 8 and 12 after CMV inoculation, and virus yields in culture supernatants were increased after the inoculation. In both types of cells, viral immediately early 1 (IE1) protein-positive nuclei were scattered at day 4 after the inoculation, and IE1 mRNA was expressed throughout day 1 to 12 after CMV inoculation. In chorion cell cultures, the number of IE1 protein-positive nuclei increased significantly at day 8 and 12 after CMV inoculation as compared to day 4, by which foci were formed. Furthermore, an evident increase in levels of lactate dehydrogenase leakage from chorion cells was observed after CMV inoculation. Contrary, these phenomena were not observed in amnion cell cultures. These results demonstrated that both chorion and amnion cells were permissive to CMV infection, while the velocity of cell-to-cell spread of CMV infection in amnion cells was much lower than that in chorion cells. Therefore, the present study suggests that CMV may replicate rapidly in the chorion cell layer and slowly in the amnion cell layer during intrauterine infection.

OBJECTIVE In order to elucidate the implication of apoptosis in lactate dehydrogenase (LDH) leakage from influenza virus-infected cells, the effects of a general caspase inhibitor, N-t-Boc-Asp(OMe)-fluoromethylketone (Boc-D-fmk), on LDH leakage, apoptosis induction and virus proliferation were examined. METHODS Cultured human fetal membrane chorion and amnion cells were incubated with or with...

Ureaplasma parvum (U. parvum) is gaining recognition as an important pathogen for chorioamnionitis and preterm premature rupture of membranes. We aimed to investigate the roles of progesterone (P4) and a novel progesterone receptor, progesterone receptor membrane component 1 (PGRMC1), in the response of fetal membranes to U. parvum. Fetal membrane cells (amnion, chorion and decidua) were isolat...

Although mesenchymal stem cells (MSCs) can be obtained from the fetal membrane (FM), little information is available regarding biological differences in MSCs derived from different layers of the FM or their therapeutic potential. Isolated MSCs from both amnion and chorion layers of FM showed similar morphological appearance, multipotency, and cell-surface antigen expression. Conditioned media o...
متن کاملFunction and failure of the fetal membrane: Modelling the mechanics of the chorion and amnion
The fetal membrane surrounds the fetus during pregnancy and is a thin tissue composed of two layers, the chorion and the amnion. While rupture of this membrane normally occurs at term, preterm rupture can result in increased risk of fetal mortality and morbidity, as well as danger of infection in the mother. Although structural changes have been observed in the membrane in such cases, the mecha...
