Abstract:
Background: The intrauterine existence of fetus is dependent on one vital organ 'the placenta’. The placenta reflects the status of maternal hypertension as it is the mirror of maternal and fetal health. The hypertensive disorders complicate 5-10% of all pregnancies and form a dangerous triad with haemorrhage and infection that contributes greatly to maternal morbidity and mortality. The fetus is dependent on placenta for growth and development. Many disorders of pregnancy like hypertension are accompanied by gross and histological changes in placenta. Aim of the study was to study the various

Fetal growth restriction (FGR) is a leading cause of perinatal morbidity and mortality. Altered placental formation and functional capacity are major contributors to FGR pathogenesis. Relating placental structure to function across the placenta in healthy and FGR pregnancies remains largely unexplored but could improve understanding of placental diseases. We investigated integration of these parameters spatially in the term human placenta using predictive modelling.

Existence of secretory granules and exocytosis during secretion of human chorionic gonadotropin (hCG) in human placenta has been a point of controversy. Using two methods, the highly sensitive avidin-biotin complex (ABC) method and the protein A-gold technique, for immunochemical identification of beta-hCG on electron microscopic sections, we have examined placentas at 8-10 weeks gestation and at term for the presence of secretory granules. First-trimester placentas demonstrated plentiful syncytiotrophoblast cytoplasmic granules, some undergoing exocytosis, when stained using specific beta-hCG

Abstract:
The use of the mouse as a model organism is common in translational research. This mouse–human similarity holds true for placental development as well. Proper formation of the placenta is vital for development and survival of the maturing embryo. Placentation involves sequential steps with both embryonic and maternal cell lineages playing important roles. The first step in placental development is formation of the blastocyst wall (approximate embryonic days [E] 3.0-3.5). After implantation (∼E4.5), extraembryonic endoderm progressively lines the inner surface of the blastocyst wall (∼E4.5-5.0)
