Heparin-binding EGF-like growth factor (HB-EGF), an EGF family member, stimulates differentiation and invasive capacity of extravillous trophoblasts in vitro. Trophoblast expression and maternal levels of HB-EGF are reduced at term in women with preeclampsia, but it is uncertain whether HB-EGF is downregulated earlier when it may contribute to placental insufficiency. A nonhuman primate model has been established in which trophoblast remodeling of the uterine spiral arteries is suppressed by shifting the rise in estrogen from the second to the first trimester of baboon pregnancy. In the present study, we used this model to determine if placental HB-EGF is altered by prematurely elevating estrogen early in baboon gestation. Uterine spiral artery remodeling and placental expression of HB-EGF and other EGF family members were assessed on day 60 of gestation in baboons treated with estradiol (E2) daily between days 25 and 59 of gestation (term\u2009=\u2009184 days). The percentages of spiral artery remodeling were 90, 84 and 70% lower (P\u2009&amp;lt;\u20090.01), respectively, for vessels of 26\u201350, 51\u2013100 and &amp;gt;100 \u00b5m diameter in E2-treated compared with untreated baboons. HB-EGF protein quantified by immunocytochemical staining\/image analysis was decreased three-fold (P\u2009&amp;lt;\u20090.01) in the placenta of E2-treated versus untreated baboons, while amphiregulin (AREG) and EGF expression was unaltered. Therefore, we propose that HB-EGF modulates the estrogen-sensitive remodeling of the uterine spiral arteries by the extravillous trophoblast in early baboon pregnancy.<\/jats:p>","DOI":"10.1530\/rep-19-0487","type":"journal-article","created":{"date-parts":[[2020,4,9]],"date-time":"2020-04-09T12:03:38Z","timestamp":1586433818000},"page":"31-37","update-policy":"https:\/\/doi.org\/10.1530\/crossmarkpolicy-11","source":"Crossref","is-referenced-by-count":1,"title":["Baboon
