Decidual spiral artery remodelling begins before cellular interaction with cytotrophoblasts

CM Craven, T Morgan, K Ward - Placenta, 1998 - Elsevier
Endometrial arteries undergo structural alterations during pregnancy to increase blood flow
to the intervillous space. It is hypothesized that physiologic change in decidual arteries is
similar to vascular remodelling seen in other organs. Histologic features of spiral arteries in
secretory endometrial biopsies were compared blindly to decidual arteries from elective
abortions. Similar sections were stained for trophoblastic and vascular antigens. Spiral
arteries in endometrium from ectopic (tubal) and intrauterine pregnancies were compared …
