As a result of the disease, patients suffer from high blood sugar and the inability to obtain energy effectively from food. Diabetes mellitus can lead to life-threatening complications such as blindness, cardiovascular disease and diabetic coma. Diabetes can arise from defective insulin hormone production (usually related to type 1 diabetes mellitus or insulin-dependent diabetes mellitus (IDDM)) and/or defective insulin hormone function (related to type 2 diabetes mellitus). IDDM usually occurs in young people and can cause many serious health problems. There are several treatments which been investigated and applied in patients. Among them, stem cell therapy (especially hematopoietic stem cell therapy) has great potential to treat diabetes due to its many distinct advantages. The review will focus on diabetes mellitus, hematopoietic stem cells, and the novel hematopoietic stem cell therapy in diabetes mellitus type 1 treatment.</p> 2017-11-28T00:00:00+07:00 ##submission.copyrightStatement## http://www.cellstemcell.org/index.php/PSC/article/view/365 Transplantation of umbilical cord blood-derived mesenchymal stem cells to treat liver cirrhosis in mice: a comparison of tail and portal vein injection 2018-02-21T15:29:26+07:00 http://www.cellstemcell.org/public/journals/3/article_365_cover_en_US.jpg Trinh Van Le thnhung@hcmus.edu.vn Nam Hai Nguyen thnhung@hcmus.edu.vn Huy Quang Do thnhung@hcmus.edu.vn Huy Minh Le thnhung@hcmus.edu.vn Nhung Hai Truong thnhung@hcmus.edu.vn <p><strong>Introduction</strong>: To date, there have been many studies indicating the positive effects of stem cells on treating liver cirrhosis. In this study, we used umbilical cord blood-derived mesenchymal stem cells (UCB-MSCs) for treatment in a mouse model of liver cirrhosis. Specifically, we determined and compared the effectiveness of two methods of MSC injection (tail vein versus portal vein).</p> <p><strong>Methods</strong>: Liver cirrhosis in male Swiss mice (of age approximately 11 weeks or under) was induced by administration of carbon tetrachloride (CCl4; 1 ml/kg). One million UCB-MSCs were then transplanted into cirrhotic mice via the portal vein or tail vein. After 21 days, blood samples were collected for measurement of transaminase, bilirubin and albumin. The expression of fibrosis-associated genes, specifically procollagen – alpha 1 and integrin – beta1, were assessed using quantitative RT-PCR. The histopathology of the specimens was also evaluated using hematoxylin/eosin, Masson trichrome staining, and immunohistochemistry using collagen type 1 and alpha-SMA antibodies.</p> <p><strong>Results</strong>: After 21 days, cirrhotic mice treated with UCB-MSCs showed recovery of bilirubin index, increase of liver albumin synthesis, inhibition of fibrosis-related gene expression (e.g. procollagen – alpha 1 and integrin – beta1), and remodeling of liver histology. From comparison of the different routes of transplantation, UCB-portal route was significantly more effective than UCB-tail route at reducing aspartate transaminase (AST) activity and bilirubin index (P&lt;0.05), and inhibiting procollagen – alpha 1 and integrin – beta1 expression (P&lt;0.05). UCB-MSCs from both transfusion routes showed accelerated improvement of liver histopathology.</p> <p><strong>Conclusion</strong>: Therapeutic strategies using UCB-MSCs have proven to be promising for the treatment of liver cirrhosis. Injection of UCB-MSC via portal vein was more effective than tail vein for cirrhosis treatment.</p> <p>&nbsp;</p> 2017-09-10T03:58:34+07:00 ##submission.copyrightStatement##
