We investigated the primary hypothesis that estrogen regulates physiological postnatal vasculogenesis by modulating bioactivity of BM-derived EPCs through the estrogen receptor (ER), in cyclic hormonally regulated endometrial neovascularization. Cultured human EPCs from peripheral blood mononuclear cells (PB-MNCs) disclosed consistent gene expression of ER \u03b1 as well as downregulated gene expressions of ER \u03b2. Under the physiological concentrations of estrogen (17\u03b2-estradiol, E2), proliferation and migration were stimulated, whereas apoptosis was inhibited on day 7 cultured EPCs. These estrogen-induced activities were blocked by the receptor antagonist, ICI182,780 (ICI). In BM transplanted (BMT) mice with ovariectomy (OVX) from transgenic mice overexpressing \u03b2-galactosidase (lacZ) regulated by an endothelial specific Tie-2 promoter (Tie-2\/lacZ\/BM), the uterus demonstrated a significant increase in BM-derived EPCs (lacZ expressing cells) incorporated into neovasculatures detected by CD31 immunohistochemistry after E2 administration. The BM-derived EPCs that were incorporated into the uterus dominantly expressed ER \u03b1, rather than ER \u03b2 in BMT mice from BM of transgenic mice overexpressing EGFP regulated by Tie-2 promoter with OVX (Tie-2\/EGFP\/BMT\/OVX) by ERs fluorescence immunohistochemistry. An in vitro assay for colony forming activity as well as flow cytometry for CD133, CD34, KDR, and VE-cadherin, using human PB-MNCs at 5 stages of the female menstrual-cycle (early-proliferative, pre-ovulatory, post-ovulatory, mid-luteal, late-luteal), revealed cycle-specific regulation of EPC kinetics. These findings demonstrate that physiological postnatal vasculogenesis involves cyclic, E2-regulated bioactivity of BM-derived EPCs, predominantly through the ER\u03b1.<\/jats:p>","DOI":"10.1161\/circresaha.106.144006","type":"journal-article","created":{"date-parts":[[2007,7,27]],"date-time":"2007-07-27T01:36:37Z","timestamp":1185500197000},"page":"598-606","update-policy":"https:\/\/doi.org\/10.1161\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":145,"title":["Estrogen-Mediated Endothelial Progenitor Cell Biology and Kinetics For Physiological Postnatal Vasculogenesis"],"prefix":"10.1161","volume":"101","author":[{"given":"Haruchika","family":"Masuda","sequence":"first","affiliation":[{"name":"From the Department of Regenerative Medicine (H.M., M.Y., M.W., M.K., R.I., H.I., M.E., Y.I., R.T., Y.N., A.S., S.N., S.K., T.A.), Tokai University School of Medicine, Isehara, Japan;
