Subtypes of extravillous trophoblast [1279

The formation of cell columns does not result in a complete trophoblastic shell but rather in separated columns from which extravillous trophoblast cells invade maternal uterine tissues (Fig. 3.3). These cells migrate as interstitial trophoblast into the endometrial stroma, while a subset of the interstitial trophoblast further penetrates the wall of the uterine spiral arteries (intramural trophoblast), finally reaching the vessels' lumen (endovascular trophoblast) (Fig. 3.3). Some of the interstitial trophoblast cells fuse and generate the multinucleated trophoblast giant cells (Fig. 3.4) at the boundary between the endometrium and myometrium.

That is why most women find out that they are pregnant only after one month of pregnancy.
