Pericytes on placental capillaries in terminal villi preferentially cover endothelial junctions in regions furthest away from the trophoblast

Placenta, 2020
Introduction Pericytes are a common feature in the placental microvasculature but their roles are not well understood. Pericytes may provide physical or endocrine support for endothelium and in some tissues mediate vasoconstriction.

Multiscale computational modeling to quantify how spiral artery remodeling alters wall shear stress on placental villi. [PDF]

PLoS Computational Biology
Proper placental development is essential for a healthy pregnancy. It depends on the remodeling of the maternal uterine vasculature to meet fetal demands while maintaining physiological intervillous space (IVS) hemodynamics for biochemical exchange ...

MORPHOMETRIC FEATURES OF TERMINAL VILLI IN PRETERM PLACENTA

Bulletin physiology and pathology of respiration, 2018
In this study, morphometric features of terminal villi in term and preterm placentas were compared. Placentas of 13 patients whose pregnancy ended in premature birth and placentas of 35 women with physiological pregnancy and delivery at term were studied.

3-D STUDY OF VESSELS IN PERIPHERAL PLACENTAL VILLI

Image Analysis and Stereology, 2011
The microvascular bed of the human term placenta is located in the mature intermediate and terminal villi. Despite repeated studies, a commonly accepted model of its spatial organization is not yet available.

Quantification of tissue fibronectin from terminal villi of placenta. [PDF]

Biochemical Journal, 1985
Tissue fibronectin (TFn) was solubilized from the terminal villi of perfused human placentas by sequential chemical extractions and plasmin digestion. Alternatively, plasmin digestion of intact tissue solubilized all the TFn, which amounted to 1.8-2.9% of the dry weight of the villi. Concomitantly, 69% of the tissue was solubilized. The non-equilibrium

HISTOMORPHOLOGICAL AND MORPHOMETRICAL CHANGES OF PLACENTAL TERMINAL VILLI OF NORMOTENSIVE AND HYPERTENSIVE MOTHERS

International Journal of Medical Sciences and Pharma Research, 2015
Background & Objectives: Placental examination has clinical value in preeclampsia (PE) and IUGR. The luminal diameter of the uterine spiral arterioles in women with PE is narrowed leading to placental ischemia thus causing fetal hypoxia and pathological ...

Morphometric investigations of terminal villi of diabetic placentas in relation to the White classification of diabetes mellitus [PDF]

Journal of Perinatal Medicine, 1987
In this morphometric study, terminal villi of 22 placentas of maternal diabetes mellitus were compared with the results in terminal villi of 22 normal placentas. The results demonstrate that there is a distinct retardation in maturation, statistically significant with bigger cross sectional surfaces of the terminal villi, particularly, when classified ...

Coronavirus disease 2019 (Covid-19) during pregnancy: Pathomorphological changes in the terminal villi of the placenta.

Polski Merkuriusz Lekarski
Aim: To investigate the pathomorphological changes in the terminal chorionic villi during COVID-19 in pregnant women. Materials and Methods: A total of 123 placentas were studied in cases of live term births (groups І) and antenatal asphyxia (groups ІІ). The subgroups were defined as follows: II.2 and I.2 (post-COVID interval of 1–4 weeks); I.1 and II.
