Three‐dimensional morphological revealing of human placental villi with common obstetric complications via optical coherence tomography [PDF]

Bioengineering and Translational Medicine, 2023
Placental villi play a vital role in human fetal development, acting as the bridge of material exchange between the maternal and fetal. The abnormal morphology of placental villi is closely related to placental circulation disorder and pregnancy ...

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.

Three-dimensional modeling of human placental terminal villi [PDF]

Placenta, 2016
Placental transport is the main factor affecting the health and development of the fetus. Due to the placenta's geometrical and mathematical complexity, the structure-function relations of placental terminal villi have not been successfully modeled.

Arrangement of collagen fibers in human placental stem villi

Acta Histochemica, 2008
The aim of the study was to investigate the arrangements and related localization patterns of different collagen types in the stroma of placental stem villi by immunohistochemistry and electron microscopy. A total of 14 normal human term placental tissue samples were studied. Immunohistochemistry was performed in order to localize collagen types I, III,

Thyroid hormone transport and metabolism are disturbed in the placental villi of miscarriage [PDF]

Reproductive Biology and Endocrinology, 2023
Background It has been long known that thyroid hormone regulates placental villi development, which is associated with the occurrence of miscarriage. However, whether abnormal thyroid hormone metabolism and transport in placental villi are involved in ...

Ultrastructural and Immunohistochemical Features of Telocytes in Placental Villi in Preeclampsia. [PDF]

Sci Rep, 2018
AbstractA new cell type, interstitial Cajal-like cell (ICLC), was recently described in different organs. The name was recently changed to telocytes (TCs), and their typical thin, long processes have been named telopodes (Tp). TCs regulate the contractile activity of smooth muscle cells and play a role in regulating vessel contractions.

An exploratory study on the placental efficiency, histomorphometric characteristics, hormonal shifts, and oxidative stress in dromedary camels with dystocia [PDF]

Frontiers in Veterinary Science
The study investigated placental efficiency, histomorphometry, and hormonal concentrations (progesterone, estradiol 17β, and cortisol) alongside oxidative stress indicators (malondialdehyde (MDA) and total antioxidant capacity (TAC)) and performed ...

Glucose metabolism by human placental villi [PDF]

Biochemical Journal, 1967
1. Glucose phosphorylation rates of about 1 mumole/g./min. have been measured at room temperature in homogenates of human placental chorionic villi, and these rates are relatively constant throughout gestation. 2. This reaction has an apparent K(m) for glucose of 3x10(-5)m both in early and term placenta. 3.
