[ 1 ] - Laminin matrix promotes hepatogenic terminal differentiation of human bone marrow mesenchymal stem cells

Objective(s):The application of stem cells holds great promises in cell transplants. Considering the lack of optimal in vitro model for hepatogenic differentiation, this study was designed to examine the effects of laminin matrix on the improvement of in vitro differentiation of human bone marrow mesenchymal stem cells (hBM-MSC) into the more functional hepatocyte-like cells. Materials and Met...

[ 2 ] - تعیین سطح سرمی کمپلکس IgA-α1-antitrypsin در بیماران مبتلا به آرتریت روماتوئید

  چکید ه   سابقه و هدف   آرتریت روماتوئید یک بیماری مزمن التهابی شدید می‌باشد. در بیماری‌های التهابی از جمله آرتریت روماتوئید میزان IgA در سرم افزایش می‌یابد که به‌دنبال آن IgA اضافی می‌تواند بابرخی از پروتئین‌های موجود درسرم از جمله آلفا-1-آنتی تریپسین ( a 1 AT ) میانکنش داشته و تشکیل کمپلکس غیرایمنی بدهد. آزمایش‌های سرولوژی رایج تشخیصی برای آرتریت روماتوئید از جمله RF ، ESR وCRP در مواردی پاس...

[ 3 ] - تاثیر سلول‌های بنیادی مشتق از بافت چربی بر فاکتورهای التهابی مؤثر در ترمیم زخم دیابتی مدل حیوانی

Background and purpose: Chronic non-healing diabetic wounds are a major medical challenge worldwide. Stem cell therapy has been developed as a new approach in the management of such wounds that need to be explored further. In the present study we aimed to evaluate the effects of adipose derived mesenchymal stem cells (ADSCs) on gene expression level of some important inflammatory factors involv...

[ 6 ] - Expression of Recombinant Alpha-1 Antitrypsin in CHO and COS-7 Cell Lines Using Lentiviral Vector

In this study, in order to facilitate and accelerate the production of eukaryotic protein alpha 1-antitrypsin (AAT) with correct post-translational modifications, a protein production system based on the transduction of CHO and COS-7 cells using lentiviral vectors was developed. Human AAT cDNA was cloned into a replication-defective lentiviral vector. The transgene AAT-Jred chimer was transferr...

[ 7 ] - Raman Spectroscopic Characterization of Hepatic Differentiation of Mesenchymal Stem Cells

Background and Aims: Mesenchymal stem cells (MSCs) are a preferred cell source for the generation of hepatocyte-like cells in regenerative medicine. They can be isolated from different sources, including adipose tissues. The Raman spectroscopy approach was evaluated for quick and efficient identification of MSCs differentiation status and a broader perspective on cell differentiation. Material...
