Isolation of Primary Human Decidual Cells from the Fetal Membranes of Term Placentae Tali Farine1,2, Michael Parsons2, Stephen Lye1,2,3, Oksana Shynlova1,2,3 1Department of Physiology, University of Toronto, 2Lunenfeld-Tanenbaum Research Institute, Sinai Health System, 3Department of Obstetrics and Gynecology, University of Toronto This protocol demonstrates a method for the isolation of primary human decidual cells collected from the fetal membranes of term placentae which can be used for a variety of applications (i.e. immunocytochemistry, flow cytometry, etc.) aiming to study the role of different cell populations in pregnancy complications.

Differential Expression of Myometrial AP-1 Proteins During Gestation and Labour Journal of Cellular and Molecular Medicine. | Pubmed ID: 28945005 Preterm labour (PTL) is a leading cause of perinatal mortality and postnatal morbidity. Contractions of the uterine muscle (myometrium) that determine the onset of labour depend on the expression of contraction-associated proteins (CAPs, i.e. connexin43) regulated by dimeric AP-1 transcription factors. Here, we examined subcellular (by immunoblotting) and tissue expression (by immunohistochemistry) of myometrial AP-1 proteins (cJUN, JUNB, JUND, cFOS, FOSB, FRA1, FRA2) throughout gestation and TL in different species (mouse, rat and human). To identify the critical AP-1 members associated with preterm birth, we studied their expression in mouse model of 'infectious' (LPS-induced) and 'sterile' (RU486-induced) PTL. We found that (1) myometrial AP-1 composition is preserved in vivo between different species (rodents and human) indicating that Fos/Jun heterodimer (i.e. FRA2/JUND) may be indispensable for labour initiation. (2) Our in vivo study using murine models of gestation shows that there is a similarity in the myometrial AP-1 protein composition during TL and pathological PTL of different aetiology suggesting the involvement of similar molecular machinery in the induction of labour. (3) This study is first comprehensive protein analysis of seven AP-1 members in human labouring versus non-labouring myometrium, showing their cellular expression and tissue distribution in relation to labour status.
