1. The main source of PGF during pregnancy is the placental trophoblast . 2. In this way the epiblastic cells migrate between the embryoblast and trophoblast . 3. Synyctin-1 mediated trophoblast fusion is essential for normal placental development. 4. These cells differentiate into many placental cells types, including extravillous trophoblast cells. 5. The outer layer of the blastocyst consists of cells collectively called the trophoblast . 6. Extravillous trophoblast grow out from the placenta and penetrate into the decidualised uterus. 7. PGF is also expressed in many other tissues, including the villous trophoblast . 8. Antibodies against phosphatidylserine and phosphatidylethanolamine are against the trophoblast . 9. Knocking out mTORC1 results in embryonic lethality due to lack of trophoblast development. 10. Injecting trophoblast cells in humans sounds like an exceptionally bad idea to me.
