Present clinical therapies aimed at alleviating peritoneal fibrosis have been largely inadequate. Mesenchymal stem cells (MSCs) are efficient for repairing injuries and reducing fibrosis. This study was designed to investigate the effects of MSCs on injured mesothelial cells and peritoneal fibrosis. METHODOLOGY/PRINCIPAL FINDINGS: Rat bone marrow-derived MSCs (5 x 10(6)) were injected into Sprague-Dawley (SD) rats via tail vein 24 h after peritoneal scraping. Distinct reductions in adhesion formation; infiltration of neutrophils, macrophage cells; number of fibroblasts; and level of transforming growth factor (TGF)-beta1 were found in MSCs-treated rats. The proliferation and repair of peritoneal mesothelial cells in MSCs-treated rats were stimulated. Mechanically injured mesothelial cells co-cultured with MSCs in transwells showed distinct increases in migration and proliferation. In vivo imaging showed that MSCs injected intravenously mainly accumulated in the lungs which persisted for at least seven days. No apparent MSCs were observed in the injured peritoneum even when MSCs were injected intraperitoneally. The injection of serum-starved MSCs-conditioned medium (CM) intravenously reduced adhesions similar to MSCs. Antibody based protein array of MSCs-CM showed that the releasing of TNFalpha-stimulating gene (TSG)-6 increased most dramatically. Promotion of mesothelial cell repair and reduction of peritoneal adhesion were produced by the administration of recombinant mouse (rm) TSG-6, and were weakened by TSG-6-RNA interfering. CONCLUSIONS/SIGNIFICANCE: Collectively, these results indicate that MSCs may attenuate peritoneal injury by repairing mesothelial cells, reducing inflammation and fibrosis. Rather than the engraftment, the secretion of TSG-6 by MSCs makes a major contribution to the therapeutic benefits of MSCs.", "link"=>"http://www.mendeley.com/research/mesenchymal-stem-cells-attenuate-peritoneal-injury-through-secretion-tsg6", "reader_count"=>49, "reader_count_by_academic_status"=>{"Unspecified"=>1, "Professor > Associate Professor"=>6, "Researcher"=>10, "Student > Doctoral Student"=>2, "Student > Ph.

The proliferation and repair of peritoneal mesothelial cells in MSCs-treated rats were stimulated. Mechanically injured mesothelial cells co-cultured with MSCs in transwells showed distinct increases in migration and proliferation. <em>In vivo</em> imaging showed that MSCs injected intravenously mainly accumulated in the lungs which persisted for at least seven days. No apparent MSCs were observed in the injured peritoneum even when MSCs were injected intraperitoneally. The injection of serum-starved MSCs-conditioned medium (CM) intravenously reduced adhesions similar to MSCs. Antibody based protein array of MSCs-CM showed that the releasing of TNFα-stimulating gene (TSG)-6 increased most dramatically. Promotion of mesothelial cell repair and reduction of peritoneal adhesion were produced by the administration of recombinant mouse (rm) TSG-6, and were weakened by TSG-6-RNA interfering.</p> <h3>Conclusions/Significance</h3><p>Collectively, these results indicate that MSCs may attenuate peritoneal injury by repairing mesothelial cells, reducing inflammation and fibrosis. Rather than the engraftment, the secretion of TSG-6 by MSCs makes a major contribution to the therapeutic benefits of MSCs.</p> </div>", "links"=>[], "tags"=>["mesenchymal", "cells", "attenuate", "peritoneal", "secretion", "tsg-6"], "article_id"=>121255, "categories"=>["Medicine", "Cell Biology", "Hematology", "Marine Biology", "Developmental Biology", "Cancer"], "users"=>["Nan Wang", "Qinggang Li", "Li Zhang", "Hongli Lin", "Jie Hu", "Diangeng Li", "Suozhu Shi", "Shaoyuan Cui", "Jianhui Zhou", "Jiayao Ji", "Jiajia Wan", "Guangyan Cai", "Xiangmei Chen"], "doi"=>["https://dx.doi.org/10.1371/journal.pone.0043768.s001", "https://dx.doi.org/10.1371/journal.pone.0043768.s002", "https://dx.doi.org/10.1371/journal.pone.0043768.s003", "https://dx.doi.org/10.1371/journal.pone.0043768.s004", "https://dx.doi.org/10.1371/journal.pone.0043768.s005", "https://dx.doi.org/10.1371/journal.pone.0043768.s006", "https://dx.doi.org/10.1371/journal.pone.0043768.s007"], "stats"=>{"downloads"=>2, "page_views"=>8, "likes"=>0}, "figshare_url"=>"https://figshare.com/articles/Mesenchymal_Stem_Cells_Attenuate_Peritoneal_Injury_through_Secretion_of_TSG_6/121255", "title"=>"Mesenchymal Stem Cells Attenuate Peritoneal Injury through Secretion of TSG-6", "pos_in_sequence"=>0, "defined_type"=>4, "published_date"=>"2012-08-17 00:20:55"}
