Introduction: Preconditioning of mesenchymal stem cells (MSCs) is a promising strategy to enhance the therapeutic properties of transplanted MSCs. In this study, we investigated the synergistic effects of treadmill exercise and dimethyloxalylglycine (DMOG)-preconditioned stem cells in an Alzheimer’s disease (AD) model. Materials and Methods: DMOG- treated MSCs were intravenously transplanted in...
Background : Genetic manipulation is an effective strategy to protect cells against environmental damages and enhance their capabilities for therapeutic usage. In order to avoid unwanted side effects, such as cancers, the expression of genes should be temporary increased. The aim of this study was to clone and temporary increased expression of a cell protective gene, Metallothionein 1 (MT1) in ...
BACKGROUND Bone marrow mesenchymal stem cells (MSCs) are one of the undifferentiated multipotential cell sources of human body. MSCs have the capacity to form a variety of cell types, especially chondrocytes and osteocytes. Learning about responses of MSCs to external milieu and chemical factors such as pH could recommend new approaches for preparation of suitable scaffolds for bone and cartila...
up-regulation of cd4+cd25+cd127low/- regulatory t cells (tregs) is a new target in the treatment of asthma. human bone marrow mesenchymal stem cells can up-regulate cd4+cd25+cd127low/- regulatory t cells in vitro, meanwhile, heme oxygenase-1 (ho-1) plays an important role in the development and maintenance of cd4+cd25+ regulatory t cells. however the mechanism has not yet been adequately under...
Background Bone marrow and adipose tissue are two main sources of mesenchymal stem cells (MSCs). Some of studies suggest that there are some differences in gene expression profile of MSCs-derived from various tissues. To investigate gene expression profile by qRT-PCR, an appropriate reference gene with stable expression level should be chosen for normalizing data. This study was designed to e...
Traumatic Brain Injury (TBI) is a major cause of death and disability worldwide. TBI can cause cognitive and memory function impairments which Current medical setting is not able to cure. In this study, we hypothesized that mesenchymal stem cells derived from Adipose tissue transplanted with RADA1- GGS IKVAV (GSIKVAV) can rescue cognitive function. An acute model of TBI was ca...
Recent findings in stem cell biology have opened a new window in regenerative medicine. The endometrium possesses mesenchymal stem cells (MSCs) called endometrial stem cells (EnSCs) having specific regenerative properties linked to adult stem cells. They contribute in tissue remodeling and engineering and were shown to have immuno-modulating effects. Many clinical trials were undertaken to asce...
Background & Aims : Mesenchymal stem cells (MSCs) are adult cells which are identified as non-hematopoietic and pluripotent stem cells. Specific stimulation of toll like receptors on the surface of mesenchymal stem cells could change immune responses of these cells into the pre or anti-inflammation phenotype. The aim of this study was to evaluate the effect of peptidoglycan-lipopolysacchari...
Background: Wharton’s jelly is an unlimited source of stem cells that can be used in cell therapy and tissue engineering without any ethical concern. It has been revealed the cell-free extract could be effective to induce cell differentiation. The objective of this study was to induce Wharton’s jelly-derived mesenchymal stem cells (MSCs) into hepatocyte-like cells by premeabilization of the cel...
introduction: chemokine receptors are found on the surface of stem cells. there have been 19 distinct chemokine receptors described in mammals. chemokines are major players in migration and homing. therefore, changes in their levels or function can help us to increase the migratory potential of these cells. valproic acid differs in structure from other drugs in common use. the way in which valp...
