placental tissue
Certain cells of a fertilized embryo.
The separation of the inner cell mass from the trophoblast during early embryonic development forms two distinct structures: the embryoblast and the trophoblast itself. The embryoblast eventually develops into the embryo, while the trophoblast contributes to the formation of the placenta, facilitating nutrient exchange between the mother and the developing fetus. This differentiation is crucial for establishing the early stages of pregnancy and supporting fetal development.
Golgi bodies
The centrioles within the cell form the mitotic spindle.
The muscularis layer of the gastrointestinal (GI) tract is responsible for forming sphincters. These sphincters help regulate the passage of food and fluids through different parts of the GI tract, such as the lower esophageal sphincter, pyloric sphincter, and anal sphincter.
The chorion is the outermost membrane surrounding the embryo, while the trophoblast is the outer layer of cells of the blastocyst responsible for implantation and placenta formation in early pregnancy. Specifically, the trophoblast gives rise to the chorion during embryonic development.

If your question is 'Is the trophoblast present during germ layer formation (i.e. gastrulation) ?' then the answer is YES

The outer layer of the blastocyst will become the trophoblast, which later develops into the placenta. The inner cell mass of the blastocyst will give rise to the embryo and eventually the fetus.
Net filtration pressure responsible for forming renal filtrate.
The double-walled membrane that contains the blastocyst is called the trophoblast. It plays a crucial role in implantation and later develops into the placenta.
