WebCirculating trophoblasts (cTBs) are placenta-derived tropho- blast cells, predominantly of the extra-villous trophoblast (EVT) type, which shed into the maternal circulation during placental implantation and development20,21. Even though rare in num- bers, cTBs can be enriched from the maternal circulation. WebApr 23, 2024 · Circulating fetal extravillous trophoblasts may offer a superior alternative to cell-free fetal DNA for noninvasive prenatal testing. Cells of fetal origin are a pure source of fetal genome; hence, unlike the cell-free noninvasive prenatal test, the fetal cell-based noninvasive prenatal test is not expected to be affected by maternal DNA. boyd goodsell ladera ranch ca
