This study was performed to examine the capability of human mesenchymal stem cells (MSCs) overexpressing hepatocyte growth factor (HGF) to inhibit collagen deposition in rat model of bladder outlet obstruction (BOO). HGF is known for its antifibrotic effect and the most promising agent for treating bladder fibrosis. BM3.B10 stable immortalized human MSC line (B10) was transduced to encode human HGF with a retroviral vector was prepared (B10.HGF). Two weeks after the onset of BOO, B10, and B10.HGF cells were injected into the rat's bladder wall. After 4 weeks, bladder tissues were harvested and Masson's trichrome staining was performed. Transgene expression in HGF-expressing B10 cells was demonstrated by reverse transcriptase polymerase chain reaction and immunohistochemical staining, and the high levels of HGF secreted by B10. HGF cells was confirmed by ELISA. The mean bladder weight in BOO rats was 5.8 times of the normal controls, while in animals grafted with B10.HGF cells, the weight was down to four times of the control [90.2 \u00b1 1.6 (control), 89.9 \u00b1 2.8 (sham), 527.9 \u00b1 150.9 (BOO), 447.7 \u00b1 41.0 (BOO + B10), and 362.7 \u00b1 113.2 (BOO + B10. HGF)]. The mean percentage of collagen area increased in BOO rats, while in the animals transplanted with B10.HGF cells, the collagen area decreased to the normal control level [12.2 \u00b1 1.3, (control), 12.8 \u00b1 1.1 (sham), 26.6 \u00b1 2.7 (BOO), 19.9 \u00b1 6.0 (BOO + B10), and 13.3 \u00b1 2.1 (BOO + B10.HGF)]. The expression of collagen and TGF-\u03b2 protein increased after BOO, while the expression of HGF and c-met protein increased in the group with B10.HGF transplantation after BOO. Intercontraction interval decreased after BOO, but it recovered after B10.HGF transplantation. Maximal voiding pressure (MVP) increased after BOO, and it recovered to levels of the normal control after transplantation of B10.HGF cells. Residual urine volume (RU) increased after BOO, but the RU increase was not reversed by transplantation of B10.HGF cells. Human MSCs overexpressing HGF inhibited collagen deposition and improved cystometric parameters in bladder outlet obstruction of rats. The present study indicates that transplantation of MSCs modified to overexpress HGF could serve as a novel therapeutic strategy against bladder fibrosis in patients with bladder outlet obstruction.<\/jats:p>","DOI":"10.3727\/096368912x637488","type":"journal-article","created":{"date-parts":[[2012,10,24]],"date-time":"2012-10-24T06:20:12Z","timestamp":1351059612000},"page":"1641-1650","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":61,"title":["Mesenchymal Stem Cells Overexpressing Hepatocyte Growth Factor (HGF) Inhibit Collagen Deposit and Improve Bladder Function in Rat Model of Bladder Outlet Obstruction"],"prefix":"10.1177","volume":"21","author":[{"given":"Yun Seob","family":"Song","sequence":"first","affiliation":[{"name":"Department of Urology, Soonchunhyang University School of Medicine, Seoul, South Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hong Jun","family":"Lee","sequence":"additional","affiliation":[{"name":"Medical Research Institute, Chung-Ang University College of Medicine, Seoul, South Korea"},{"name":"Division of Neurology, Department of Medicine, UBC Hospital, University of British Columbia, Vancouver, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Seung Hwan","family":"Doo","sequence":"additional","affiliation":[{"name":"Department of Urology, Soonchunhyang University School of Medicine, Seoul, South Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sun Ju","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Medicine, Kyunghee University School of Medicine, Seoul, South Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Inja","family":"Lim","sequence":"additional","affiliation":[{"name":"Department of Physiology, Chung-Ang University College of Medicine, Seoul, South Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kyu-Tae","family":"Chang","sequence":"additional","affiliation":[{"name":"National Primate Research Center, Korea Research Institute of Bioscience and Biotechnology, Ochang, South Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Seung U.","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Urology, Soonchunhyang University School of Medicine, Seoul, South Korea"},{"name":"Division of Neurology, Department of Medicine, UBC Hospital, University of British Columbia, Vancouver, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2012,8,1]]},"reference":[{"key":"bibr1-096368912X637488","doi-asserted-by":"publisher","DOI":"10.1016\/j.clinbiochem.2007.04.017"},{"key":"bibr2-096368912X637488","first-page":"157","volume":"75","author":"Baskin L.
