After the pupils begin to function, the double layer of epithelial cells separates at the apical cell contacts, leading to defoliation of its posterior pigment epithelial cell layer, and extracellular material begins to accumulate in the basement membrane zones of the iris. In contrast to the iris epithelia, where no clear signs of cellular atrophy were detected, the lack of type XVIII collagen resulted in atrophy of the pigmented epithelial cells of the ciliary body, and there were also ultrastructural abnormalities in the basement membrane zones. These changes did not lead to chronically elevated intraocular pressures, however. Our results indicate that type XVIII collagen is needed for the integrity of the epithelial basement membranes of the iris and the ciliary body and that its gene should therefore be taken into account as a new potential cause of anterior segment disorders in the eye.\n                  <\/jats:p>","DOI":"10.1096\/fj.02-1001fje","type":"journal-article","created":{"date-parts":[[2003,10,6]],"date-time":"2003-10-06T20:15:33Z","timestamp":1065471333000},"page":"2257-2259","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":63,"title":["Lack of type XVIII collagen results in anterior ocular defects"],"prefix":"10.1096","volume":"17","author":[{"given":"Ritva","family":"Ylik\u00e4rpp\u00e4","sequence":"first","affiliation":[{"name":"Collagen Research Unit, Biocenter Oulu and Department of Medical Biochemistry and Molecular Biology University of Oulu Oulu Finland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lauri","family":"Eklund","sequence":"additional","affiliation":[{"name":"Collagen Research Unit, Biocenter Oulu and Department of Medical Biochemistry and Molecular Biology University of Oulu Oulu Finland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Raija","family":"Sormunen","sequence":"additional","affiliation":[{"name":"Biocenter Oulu and Department of Pathology University of Oulu Oulu Finland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Antti I.","family":"Kontiola","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology Helsinki University Central Hospital Helsinki Finland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Aino","family":"Utriainen","sequence":"additional","affiliation":[{"name":"Collagen Research Unit, Biocenter Oulu and Department of Medical Biochemistry and Molecular Biology University of Oulu Oulu Finland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marko","family":"M\u00e4\u00e4tt\u00e4","sequence":"additional","affiliation":[{"name":"Biocenter Oulu and Department of Pathology University of Oulu Department of Ophthalmology University Hospital of Helsinki Helsinki Finland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Naomi","family":"Fukai","sequence":"additional","affiliation":[{"name":"Department of Cell Biology Harvard Medical School Boston Massachusetts"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bj\u00f6rn R.","family":"Olsen","sequence":"additional","affiliation":[{"name":"Department of Cell Biology Harvard Medical School Boston Massachusetts"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Taina","family":"Pihlajaniemi","sequence":"additional","affiliation":[{"name":"Collagen Research Unit, Biocenter Oulu and Department of Medical Biochemistry and Molecular Biology University of Oulu Oulu Finland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2003,10,2]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.91.10.4229"},{"key":"e_1_2_6_3_1","doi-asserted-by":"publisher","DOI":"10.1006\/scdb.1996.0082"},{"key":"e_1_2_6_4_1","doi-asserted-by":"publisher","DOI":"10.1074\/jbc.273.39.25404"},{"key":"e_1_2_6_5_1","doi-asserted-by":"publisher","DOI":"10.1006\/geno.1996.0139"},{"key":"e_1_2_6_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0092-8674(00)81848-6"},{"key":"e_1_2_6_7_1","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.92.19.8763"},{"key":"e_1_2_6_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0002-9440(10)65603-9"},{"key":"e_1_2_6_9_1","doi-asserted-by":"publisher","DOI":"10.1247\/csf.27.9"},{"key":"e_1_2_6_10_1","doi-asserted-by":"publisher","DOI":"10.1093\/hmg\/9.13.2051"},{"key":"e_1_2_6_11_1","doi-asserted-by":"publisher","DOI":"10.1086\/344695"},{"key":"e_1_2_6_12_1","doi-asserted-by":"publisher","DOI":"10.1093\/emboj\/21.7.1535"},{"issue":"3","key":"e_1_2_6_13_1","first-page":"181","article-title":"Retinal detachment and encephalocele","volume":"8","author":"Knobloch W.
