Umbilical Cord Blood-Derived Mesenchymal Stem Cells Inhibit, But Adipose Tissue-Derived Mesenchymal Stem Cells Promote, Glioblastoma Multiforme Proliferation

Cytotoxicity of Chitosan Derived from Shrimp for Bone Scaffold on Adipose Tissue-Derived Mesenchymal Stem Cells

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...

Tumorigenicity Evaluation of Umbilical Cord Blood-derived Mesenchymal Stem Cells

Mesenchymal stem cells (MSCs) have been identified in multiple types of tissue and exhibit characteristic self-renewal and multi-lineage differentiation abilities. However, the possibility of oncogenic transformation after transplantation is concerning. In this study, we investigated the tumorigenic potential of umbilical cord blood-derived MSCs (hUCB-MSCs) relative to MRC-5 and HeLa cells (neg...

Platelet-derived Microparticles increase the Expression of hTERT Gene in Umbilical Cord Mesenchymal Stem Cells

Background: Mesenchymal stem cells have been widely considered in clinical researches because of their self-renewality and differentiation into various tissues. Nevertheless, their limited in vitro life span, which occurs only after several divisions, makes some changes in these cells, which affects all of their characteristics and remarkably reduces their application. In this study, the effect...

Study of telomerase activity, proliferation and differentiation characteristics in umbilical cord blood mesenchymal stem cells

In recent years, considerable advances have been made in the field of regenerative medicine. Unlikeembryonic stem cells, which pose the problems of ethical concerns and cause severe immunological reactions as well as neoplasma formation after transplantation, umbilical cord blood is a primitive source ofmesenchymal stem cells that covers the benefits of both embryonic and adult stem cells. It h...
