چکیده
Backgrounds: Hepatic fibrosis is one of the main reasons for mortality in the world, and there isno definite cure for it. The lack of effective treatments for Hepatic fibrosis is a major globalproblem. When hepatic stellate cells (HSCs) activate, the expression of TGF-β and αSMA(Hepatic Fibrogenic genes) will increase, which leads to hepatic fibrosis. At present, there islittle information on the action mechanism of exosomes derived from Whartons’ jellymesenchymal stem cells (WJ-MSCs) in the treatment of liver fibrosis. So we decided to study theeffect of exosomes of WJ-MSCs in the clinic and remedy.In this study, we investigated the effects of exosomes on genes involved in hepatic fibrosisprogression in the cholesterol-activated human HSCs.Materials and Methods: In this experimental study, the HSCs were cultured in a DMEMmedium with ۱۰% Fetal Bovine Serum, and then the cells were treated with ۱۰۰μM Cholesterolto be activated. After that, the cells were treated with the ۲۰μM exosomes. Finally, QuantitativeReal-time PCR and Western blotting techniques were performed.Results: Exosome treatment significantly reduced the expression of TGF-β and αSMA genes inthe cholesterol-activated HSCs (P< ۰.۰۵). Exosomes Treatment decreased the activation of HSCsby inhibiting the level of Smad۳C phosphorylation.Conclusion: In summary, treatment with exosomes of WJ-MSCs reduced HSC activation invitro. The relevant mechanism is through inhibition of the TGF-β / Smad۳C signaling pathway.According to these results, exosomes derived from WJ-MSCs can be introduced as a potentialtherapeutic agent for the treatment of hepatic fibrosis.کلیدواژه ها

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.
کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
