In-vitro Differentiation of Human Umbilical Cord Wharton’s Jelly Mesenchymal Stem Cells to Insulin-Producing Cells
Background & Objective: Diabetes is a major chronic metabolic disease in the world. Islet transplantation is a way to treat diabetes. Unfortunately, this method is restricted due to graft rejection and lack of donor islets. Mesenchymal Stem Cells (MSCS) have the ability to differentiate into Insulin-Producing Cells (IPCs). In this study, Human Umbilical Mesenchymal Stem Cells (HUMSCS) were induced to differentiate into pancreatic β-like cells. Materials & Methods: The samples were collected after cesarean section delivery at Hafez hospital. HUMSCS were cultured in sterile condition, in three steps for 20 days in DMEM-F12, Retinoic Acid (RA), Epidermal Growth Factor (EGF), exendin-4, Fetal Bovine Serum (FBS), and antibiotic. Then, they were differentiated into IPC. DTZ staining employed for determining the presence of insulin and Reveres Transcription- Polymerase Chain Reaction (RT-PCR) was done for identifying of gene expression including insulin, PDX1, and NGN3. The Insulin concentration was also evaluated by Immunoradiometric assay. Results: HUMSCS gradually changed from fibroblast-shaped cells to epithelial-like cells and eventually to IPC under special conditions. RT-PCR experiments revealed that these cells expressed insulin, PDX1, and NGN3 genes. The cells became red color when stained with DTZ and the insulin secretion was confirmed. Conclusion: HUMSCS have the ability to differentiate into islet-like cells in vitro and may be a new potential source for cell transplantation in diabetes treatment.
Differentiation of Human Adipose Tissue-Derived Mesenchymal Stem Cells into Insulin Producing Cells Using Minimal Differentiation Factors
Background & Aims: Type 1 diabetes, or insulin-dependent diabetes, is an autoimmune disease in which pancreatic beta cells are destroyed by the immune system. Hitherto, no definite treatment has been found for this condition. Mesenchymal stem cells (MSCs) are multipotent, self-renewing cells that have the ability to differentiate into mesodermal tissues. This ability has attracted the attention...متن کامل
Differentiation Potential of Nestin (+) and Nestin (-) Cells Derived from Human Bone Marrow Mesenchymal Stem Cells into Functional Insulin Producing Cells
The feasibility of isolating and manipulating mesenchymal stem cells (MSCs) from human patients provides hope for curing numerous disease and disorders. Recent phenotypic analysis showed heterogeneity of MSCs. A nestin progenitor cell is a subpopulation within MSCs which plays a role in pancreas regeneration during embryogenesis. This study aimed to separate nestin (+) cells from human bone mar...متن کامل

Differentiation of Umbilical Cord Lining Membrane-Derived Mesenchymal Stem Cells into Endothelial-Like Cells
Background: Stem cell therapy for the treatment of vascular-related diseases through functional revascularization is one of the most important research areas in tissue engineering. The aim of this study was to investigate the in vitro differentiation of umbilical CL-MSC into endothelial lineage cells. Methods: In this study, isolated cells were characterized for expression of MSC-specific marke...متن کامل
Differentiation of PDX1 gene-modified human umbilical cord mesenchymal stem cells into insulin-producing cells in vitro.
Mesenchymal stem cells (MSCs) have significant advantages over other stem cell types, and greater potential for immediate clinical application. MSCs would be an interesting cellular source for treatment of type 1 diabetes. In this study, MSCs from human umbilical cord were differentiated into functional insulin-producing cells in vitro by introduction of the pancreatic and duodenal homeobox fac...متن کامل
