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.
