A pregnancy at risk for adenosine deaminase deficiency and severe combined immunodeficiency disease was investigated using samples of chorionic villi obtained during the eighth week of pregnancy. Adenosine deaminase levels suggested that the fetus was a probable carrier and that a diagnosis of severe combined immunodeficiency disease could be excluded. Enzyme and chromosome results were availab...

Paternally expressed gene 10 (PEG10) is an imprinted and monoallelic expressed gene. Previous study using a knockout mouse model revealed a crucial role of PEG10 in placental development, yet the exact function of PEG10 during placentation remains to be elucidated. In this study, denuded chorionic villi were prepared from first trimester human placentas, and transduced with PEG10 small interfer...

UNLABELLED The objective of the present study was to evaluate whether placental mesenchymal stromal cells (PDMSCs) derived from normal and preeclamptic (PE) chorionic villous tissue presented differences in their cytokines expression profiles. Moreover, we investigated the effects of conditioned media from normal and PE-PDMSCs on the expression of pro-inflammatory Macrophage migration Inhibitor...

We describe the distribution of indoleamine 2,3-dioxygenase 1 (IDO1) in vascular endothelium of human first-trimester and term placenta. Expression of IDO1 protein on the fetal side of the interface extended from almost exclusively sub-trophoblastic capillaries in first-trimester placenta to a nearly general presence on villous vascular endothelia at term, including also most bigger vessels suc...

Human papillomavirus (HPV) is an epitheliotropic virus typically infecting keratinocytes but also possibly epithelial trophoblastic placental cells. In the present study, we set out to investigate whether HPV can be recovered from transabdominally obtained placental cells to avoid any confounding contamination by HPV-infected cervical cells. Thirty-five placental samples from women undergoing t...

Meckel-Gruber syndrome (MGS) is a lethal autosomal recessive condition which is rarely reported. Polycystic kidneys, polydactyly, occipital encephalocele are the diagnostic triad for MGS. 24 year old G2P1L1 having a consanguineous marriage at 20 weeks of gestation on detailed level II anomaly scan showed bilateral enlarged polycystic kidneys with increased echogenicity, absent urinary bladder, ...

BACKGROUND Defective chorionic villous vascularization is present in pregnancies complicated by absent or abnormal embryonic development. The aim of this study was to investigate the embryonic and/or maternal genomic influence on vasculogenesis in diploid complete hydatidiform mole (CHM) and in triploid partial hydatidiform mole (PHM) in comparison with normal development. METHODS Mean villou...

The aim of the present study was to investigate the expression pattern of four DNA methyltransferases (DNMT1, DNMT3A, DNMT3B and DNMT3L) in placenta chorionic villi of early embryo growth arrest patients. Chorionic villous specimens were obtained from 40 pregnant patients diagnosed with early embryo growth arrest and 40 healthy women who underwent selective pregnancy termination. Reverse transc...
