Seventeen dysplastic kidneys (16 weeks to 7 months) and 20 normal age-matched controls were used in the study. Increased PDGF-A mRNA was detected in dysplastic compared to normal kidneys in all age groups including extensively fibrotic postnatal kidneys. An abundant PDGF-A mRNA signal was seen within the epithelial cells of cystically dilated or dysplastic tubules and within interstitial fibroblasts and disorganized primitive mesenchyme. A comparable amount of PDGF-A protein was detected by Western blotting. Procollagen I and III mRNA were increased in fibroblasts surrounding cystic and dysplastic tubules. We conclude that tubular epithelial production of PDGF-A may induce collagenous matrix production by adjacent fibroblasts, while marked up-regulation of PDGF-A by interstitial cells may be responsible for sustainable fibrogenic effects in the fetal kidney contributing to renal maldevelopment.<\/jats:p>","DOI":"10.1159\/000190164","type":"journal-article","created":{"date-parts":[[2008,12,24]],"date-time":"2008-12-24T09:02:25Z","timestamp":1230109345000},"page":"161-170","source":"Crossref","is-referenced-by-count":13,"title":["Increased Expression of Platelet-Derived Growth Factor A and Collagenous Matrix Proteins in Congenital Multicystic Renal Dysplasia"],"prefix":"10.1159","author":[{"given":"Helen","family":"Liapis","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hong","family":"Yu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alanna","family":"Flath","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"George F.","family":"Steinhardt","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2008,12,23]]},"container-title":["Nephron"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/karger.com\/article-pdf\/doi\/10.1159\/000190164","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,5,1]],"date-time":"2026-05-01T18:35:19Z","timestamp":1777660519000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000190164"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2008,12,23]]},"references-count":0,"URL":"https:\/\/doi.org\/10.1159\/000190164","archive":["Portico"],"relation":{},"ISSN":["1660-8151","2235-3186"],"issn-type":[{"value":"1660-8151","type":"print"},{"value":"2235-3186","type":"electronic"}],"subject":[],"published":{"date-parts":[[2008,12,23]]}}}
