The implantation process involves complex and synchronized molecular and cellular events
between the uterus and the implanting embryo. These events are regulated by paracrine …

Cytotrophoblastic cells (CTBs) from first trimester placenta follow one of two existing
differentiation pathways: villous CTBs (vCTBs) form a monolayer of polarized epithelial stem …

Ectopic pregnancy accounts for 2 percent of all pregnancies in the United States, and
contributes substantially to maternal morbidity and mortality. Risk factors for the …

During early human pregnancy, extravillous trophoblast (EVT) cells from the placenta invade
the uterine decidual spiral arterioles and mediate the remodelling of these vessels such that …

Implantation in the human is unique. This uniqueness is characterized on the maternal side
by a spontaneous and massive decidualization of the endometrium and on the embryonic …

Chorionic gonadotropin (CG) is indispensable for human pregnancy because it controls
implantation, decidualization, and placental development. However, its particular role in the …

Because cytotrophoblastic cells (CTB) from first-trimester placenta form columns of invasive
CTB they have been considered as a model for blastocyst implantation. This invasive …

Cytotrophoblastic cells (CTBs) from first‐trimester placenta form columns of invasive CTBs.
This invasive behavior is due to the ability of CTBs to secrete matrix metalloproteinases …

OBJECTIVE: To determine the relationship between gestational age, tubal ultrasonographic
diameter, and serum hCG levels and different stages of trophoblastic infiltration of the tubal …

BACKGROUND: Predictive factors of damage to the Fallopian tube may guide the treatment
for patients with tubal pregnancy. The aim of this study was to assess the predictive value of …
