Exosomes excreted from MSCs can reduce myocardial ischemia\/reperfusion damage and protect against acute tubular injury. However, whether MSC-derived exosomes can relieve liver fibrosis and its mechanism remain unknown. Previous work showed that human umbilical cord-MSCs (hucMSCs) transplanted into acutely injured and fibrotic livers could restore liver function and improve liver fibrosis. In this study, it was found that transplantation of exosomes derived from hucMSC (hucMSC-Ex) reduced the surface fibrous capsules and got their textures soft, alleviated hepatic inflammation and collagen deposition in carbon tetrachloride (CCl\n                    <jats:sub>4<\/jats:sub>\n                    )-induced fibrotic liver. hucMSC-Ex also significantly recovered serum aspartate aminotransferase (AST) activity, decreased collagen type I and III, transforming growth factor (TGF)-\u03b21 and phosphorylation Smad2 expression in vivo. In further experiments, we found that epithelial-to-mesenchymal transition (EMT)-associated markers E-cadherin-positive cells increased and N-cadherin- and vimentin-positive cells decreased after hucMSC-Ex transplantation. Furthermore, the human liver cell line HL7702 underwent typical EMT after induction with recombinant human TGF-\u03b21, and then hucMSC-Ex treatment reversed spindle-shaped and EMT-associated markers expression in vitro. Taken together, these results suggest that hucMSC-Ex could ameliorate CCl\n                    <jats:sub>4<\/jats:sub>\n                    -induced liver fibrosis by inhibiting EMT and protecting hepatocytes. This provides a novel approach for the treatment of fibrotic liver disease.\n                  <\/jats:p>","DOI":"10.1089\/scd.2012.0395","type":"journal-article","created":{"date-parts":[[2012,9,24]],"date-time":"2012-09-24T19:04:58Z","timestamp":1348513498000},"page":"845-854","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":791,"title":["Exosomes Derived from Human Umbilical Cord Mesenchymal Stem Cells Alleviate Liver Fibrosis"],"prefix":"10.1177","volume":"22","author":[{"given":"Tingfen","family":"Li","sequence":"first","affiliation":[{"name":"Jiangsu University","place":["People's Republic of China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yongmin","family":"Yan","sequence":"additional","affiliation":[{"name":"Jiangsu University","place":["People's Republic of China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bingying","family":"Wang","sequence":"additional","affiliation":[{"name":"Jiangsu University","place":["People's Republic of China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hui","family":"Qian","sequence":"additional","affiliation":[{"name":"Jiangsu University","place":["People's Republic of China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xu","family":"Zhang","sequence":"additional","affiliation":[{"name":"Jiangsu University","place":["People's Republic of China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Li","family":"Shen","sequence":"additional","affiliation":[{"name":"Jiangsu University","place":["People's Republic of China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mei","family":"Wang","sequence":"additional","affiliation":[{"name":"Jiangsu University","place":["People's Republic of China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ying","family":"Zhou","sequence":"additional","affiliation":[{"name":"Jiangsu University","place":["People's Republic of China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wei","family":"Zhu","sequence":"additional","affiliation":[{"name":"Jiangsu University","place":["People's Republic of China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wei","family":"Li","sequence":"additional","affiliation":[{"name":"Jiangsu University","place":["People's Republic of China"]},{"name":"China Medical City","place":["People's Republic of China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wenrong","family":"Xu","sequence":"additional","affiliation":[{"name":"Jiangsu University","place":["People's Republic of China"]},{"name":"Jiangsu University","place":["People's Republic of China"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2012,9,24]]},"reference":[{"key":"e_1_3_3_2_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1530-0277.2010.01400.x"},{"key":"e_1_3_3_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.taap.2010.11.016"},{"key":"e_1_3_3_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.fct.2010.12.006"},{"key":"e_1_3_3_5_2","doi-asserted-by":"publisher","DOI":"10.1053\/j.gastro.2008.03.002"},{"key":"e_1_3_3_6_2","doi-asserted-by":"publisher","DOI":"10.1074\/jbc.M700194200"},{"key":"e_1_3_3_7_2","doi-asserted-by":"publisher","DOI":"10.1172\/JCI0215518"},{"key":"e_1_3_3_8_2","doi-asserted-by":"publisher","DOI":"10.1002\/hep.24254"},{"key":"e_1_3_3_9_2","doi-asserted-by":"publisher","DOI":"10.1074\/jbc.M700998200"},{"key":"e_1_3_3_10_2","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0019195"},{"key":"e_1_3_3_11_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1478-3231.2008.01855.x"},{"key":"e_1_3_3_12_2","doi-asserted-by":"publisher","DOI":"10.1258\/ebm.2012.011362"},{"key":"e_1_3_3_13_2","doi-asserted-by":"publisher","DOI":"10.1152\/ajprenal.00339.2006"},{"key":"e_1_3_3_14_2","doi-asserted-by":"publisher","DOI":"10.1097\/MNH.0b013e328332fb6f"},{"key":"e_1_3_3_15_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1582-4934.2012.01597.x"},{"key":"e_1_3_3_16_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-0854.2008.00734.x"},{"key":"e_1_3_3_17_2","doi-asserted-by":"publisher","DOI":"10.1681\/ASN.2008070798"},{"key":"e_1_3_3_18_2","doi-asserted-by":"publisher","DOI":"10.1093\/ndt\/gfr015"},{"key":"e_1_3_3_19_2","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0033115"},{"key":"e_1_3_3_20_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.scr.2009.12.003"},{"key":"e_1_3_3_21_2","doi-asserted-by":"publisher","DOI":"10.2217\/rme.11.35"},{"key":"e_1_3_3_22_2","first-page":"325","article-title":"Bone marrow mesenchymal stem cells ameliorate rat acute renal failure by differentiation into renal tubular epithelial-like cells","volume":"22","author":"Qian H","year":"2008","unstructured":"Qian H, , Yang H, , Xu W, , Yan Y, , Chen Q, , Zhu W, , Cao H, , Yin Q, , Zhou H, , Mao F, , Chen Y. 2008.
