chorionic mesenchymal villus

mesenchymal villus

The first generation of a tertiary villus that is derived from a syncytial sprout by the invasion of the mesenchyme, in which blood vessels differentiate through vasculogenesis, and gradually transforms into a new immature intermediate villus. A chorionic mesenchymal villus has a thick trophoblastic covering, and cytotrophoblast cells are interposed between syncytium and the trophoblastic basal lamina over 50–100% of the surface. The stroma is characterized by loosely arranged collagen fibers that enmesh mesenchymal and some villous macrophages. The fetal capillaries are poorly developed.

Questions fréquentes

What is the chorionic mesenchymal villus?
A chorionic mesenchymal villus is a histological subdivision of the chorionic villi characterized by its core of mesenchymal connective tissue. It represents an intermediate stage of villous development between stem villi and terminal villi.
Where is the chorionic mesenchymal villus located?
Located within the placental chorionic tissue, these villi extend from the chorionic plate into the intervillous space where they are bathed in maternal blood.
What is the function of the chorionic mesenchymal villus?
The mesenchymal villi serve as structural scaffolding and contain blood vessels that facilitate nutrient and oxygen exchange between maternal and fetal circulations.
What is the chorionic mesenchymal villus connected to?
These villi are connected to the chorionic plate at their base and contain fetal capillaries that drain into larger fetal blood vessels within the villous tree.
Why is the chorionic mesenchymal villus clinically important?
Abnormal development of mesenchymal villi can indicate placental insufficiency or intrauterine growth restriction, making their morphology diagnostically significant in prenatal assessment.
