Biopsies were taken during surgery from the bladder dome, trigone, the proximal and distal urethra, vagina and vesico\u2010vaginal fascia in the region of the bladder neck.<\/jats:p><jats:p><jats:bold>Methods\n\t\t\t\t\t<\/jats:bold> Formalin\u2010fixed paraffin\u2010embedded biopsies were labelled by an avidin\u2013biotin technique with a monoclonal antibody raised against part of the nuclear matrix known as Ki\u201067 antigen.<\/jats:p><jats:p><jats:bold>Main\n\t\t\t\t\t<\/jats:bold>  <jats:bold>outcome measures<\/jats:bold> Ki\u201067 expression was assessed in the epithelial, subepithelial and muscle or deep fascial regions of all tissues and related to oestrogen status.<\/jats:p><jats:p><jats:bold>Results\n\t\t\t\t\t<\/jats:bold> Ki\u201067 expression was only found in high levels in biopsies containing squamous epithelia.

As these same squamous epithelia also consistently express oestrogen receptors, the findings suggest a mechanism by which oestrogen exerts its effect on the lower urinary tract and also provide an explanation for the success of oestrogen in the treatment of some conditions causing lower urinary tract dysfunction in postmenopausal women.<\/jats:p>","DOI":"10.1111\/j.1471-0528.2001.00210.x","type":"journal-article","created":{"date-parts":[[2003,12,22]],"date-time":"2003-12-22T17:08:18Z","timestamp":1072112898000},"page":"813-816","update-policy":"http:\/\/dx.doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Cellular proliferation in the female lower urinary tract with reference to oestrogen status"],"prefix":"10.1111","volume":"108","author":[{"given":"Peter J.","family":"Blakeman","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Paul","family":"Hilton","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Judith N.","family":"Bulmer","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2003,12,22]]},"reference":[{"key":"e_1_2_6_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0002-9378(16)39040-8"},{"key":"e_1_2_6_3_2","doi-asserted-by":"publisher","DOI":"10.1159\/000298804"},{"key":"e_1_2_6_4_2","doi-asserted-by":"publisher","DOI":"10.1159\/000293384"},{"key":"e_1_2_6_5_2","doi-asserted-by":"publisher","DOI":"10.1159\/000185111"},{"key":"e_1_2_6_6_2","doi-asserted-by":"publisher","DOI":"10.1056\/NEJM199309093291102"},{"key":"e_1_2_6_7_2","first-page":"12","article-title":"The hormones and urogenital therapy committee.
