chorionic anchoring villus

Synonyms
anchoring villus PMID: 15142834

Definition (free text, please give PubMed ID)
A distal smaller chorionic stem villus that is connected initially to the decidua and later to the developing basal plate via a cytotrophoblast cell column. A chorionic anchoring villus stabilizes the position of the villous trees in the maternal intervillous bloodstream. PMID: 15142834, PMID:32513715, doi:10.1007/978-3-030-84725-8, PMID:9260835

Preferred term label:
chorionic stem villus

Synonyms
placental stem villus PMID:9260835

Definition (free text, please give PubMed ID)
The central branch of a chorionic villous tree that arise from the chorionic plate. A chorionic stem villus is characterized by a condensed fibrous stroma in which the fetal arteries and veins as well as the arterioles and venules are embedded. It is the supporting structure of a chorioinic villous tree and represents a distributing framework for the fetal chorionic circulation, supplying the floating villi. It exhibits a diameter ranging from about 3000 μm (trunci near the chorionic plate) to 80 μm (smallest ramuli chorii). PMID:9260835, doi:10.1007/978-3-030-84725-8

Definition (free text, please give PubMed ID)
A bulbous, immature chorionic villus that is formed of loose connective tissue with few fetal vessels. A chorionic immature intermediate villus develops from a chorionic mesenchymal villus, and is is the forerunner of a chorionic stem villus. PMID:487407, PMID:9260835

Preferred term label:
chorionic mature intermediate villus

Synonyms
mature intermediate villus PMID:21452443

Definition (free text, please give PubMed ID)
A slender branch of a chorionic stem villus. A chorionic mature intermediate villus lacks fetal arterioles and venules in the stroma, which is composed of slender fetal capillaries embedded into a loose connective tissue that is rich in cells but poor in fibers. It exhibits a diameter ranging from 60 to about 100 μm. PMID:21452443, doi:10.1007/978-3-030-84725-8

Preferred term label:
chorionic terminal villus

Synonyms
terminal villus PMID:21452443

Definition (free text, please give PubMed ID)
The most distal part of a chorionic villus. A chorionic terminal villus is a grape-like structure characterized by a high degree of capillarization and highly dilated sinusoids. A terminal villus has less stroma and a discontinuous cytotrophoblast layer, and contain 4–6 fetal capillaries per cross section. It exhibits a diameter ranging from 40 to about 80 μm.

Preferred term label:
chorionic mesenchymal villus

Synonyms
mesenchymal villus (BROAD) doi:10.1007/978-3-030-84725-8

Definition (free text, please give PubMed ID)
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. doi:10.1007/978-3-030-84725-8
