trophoblast
- noun
- /ˈtroʊfəˌblæst/
- Specialized
- The findings demonstrate that malaria parasitaemia prior to 20 weeks' gestation affects placentation and may contribute to poor pregnancy outcomes due to dysregulation of trophoblast invasion.
- trophoblast cells
- trophoblast invasion
- trophoblast invades
Examples
-
Extravillous trophoblast invasion is highly regulated and is critical to establishing physiologic uteroplacental blood flow.

Evidence consistent with increased trophoblast invasion among nourished women with early pregnancy malaria parasitaemia was also found.

The first layer of cells that develops into the placenta is called the trophoblast.

Placental bed biopsies are necessary to determine if the effects of early pregnancy malaria parasitaemia on trophoblast invasion are physiological or pathological.

The blastocyst is a sphere made up of an outer layer of cells (the trophoblast), a fluid-filled cavity (the blastocoel), and a cluster of cells on the interior (the inner cell mass).
Academic text (2007) -
It contains the inner cell mass, from which embryonic stem cells are derived, and an outer layer of cells called the trophoblast that forms the placenta. (It is approximately 1/10 the size of the head of a pin.)
Academic text (2007) -
It has been previously hypothesized that malaria parasitaemia in early pregnancy disrupts trophoblast invasion, leading to diminished utero-placental blood flow and, ultimately, intrauterine growth restriction.

The trophoblast cells invade the lining of the uterus and thereby begin implantation.
-
The first layer of cells that develops into the placenta is called the trophoblast.
-
The trophoblast cells signal the macrophages to come and clean up the dead cell mess.
Synonyms
A thin outer layer that surrounds a young animal in birds, reptiles, and mammals before it hatches or is born

Morphology
trophoblast = tropho + blast
The components 'tropho' and 'blast' are specialized scientific terms and not transparent to an average learner without specific biological knowledge.
Etymology
Trophoblast comes from Greek parts troph- ('nourish') and -blast ('bud' or 'young cell'). So, the name fits: these outer early cells help 'feed' the embryo, attach it to the womb, and later form the placenta.
