چکیده

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 the AD model and the rats went on treadmill exercise for one month. Thusly, expression of bax, bcl-2, Nrf2, and NQO1 genes were assessed using real- time PCR. Results: Transplantation of DMOG-treated cells had greater effects on increasing Nrf-2 and NQ1 expression and reducing apoptosis compared to non- treated cells. Ultimately, treadmill exercises for one month along with the transplantation of DMOG- treated cells showed the highest neuroprotective effect. Conclusion: It seems that the transplantation of DMOG-treated cells beside exercise may have protective effects in the AD model via an increase in antioxidant capacity and a decrease in apoptosis.

Regenerative Effect of Bone Marrow-derived Mesenchymal Stem Cells in Thioacetamide-induced Liver Fibrosis of Rats

The present study determined the regenerative effect of bone marrow-derived stem cells (BMSCs) on thioacetamide (TA)-induced liver fibrosis in rats. A total of 30 male Wistar rats were randomly divided into sham control and treatment groups. The rats of the sham control group were subdivided into three groups and sampled on the 14th, 18th, and 20th weeks after fibrosis induction. The rats of th...

The effects of bone marrow-derived mesenchymal stem cells on ovalbumin-induced allergic asthma and cytokine responses in mice

Objective(s): Allergic Asthma is an inflammatory disease of the lungs that is characterized by increased infiltration of leukocytes into the airways, limiting the respiratory function. Studies suggest that a defective general regulatory system against inflammation could be a significant factor in allergic asthma. It has been shown that Mesenchymal stem cells (MSCs) have a cellular immunosuppres...

Calcitriol modulates the effects of bone marrow-derived mesenchymal stem cells on macrophage functions

Objective(s):Some evidence showed that calcitriol has an important role in regulating growth and differentiation of mesenchymal stem cells (MSCs). However, the interaction between mesenchymal stem cells and macrophage is not clear yet.  The current study was done to investigate the in vitro effects of calcitriol on the interactions between bone marrow-derived MSCs and rat macrophages. Material...

Harvesting of bone marrow mesenchymal stem cells from live rats and the in vitro differentiation of bone marrow mesenchymal stem cells into neuron-like cells

In the bone marrow, there are certain populations of stem cell sources with the capacity to differentiate into several different types of cells. Ideally, cell transplants would be readily obtainable, easy to expand and bank, and capable of surviving for sufficient periods of time. Bone marrow mesenchymal stem cells (BM-MSCs) possess all of these characteristics. One of the most important benefi...

Effect of bone marrow derived mesenchymal stem cells on lung pathology and inflammation in ovalbumin-induced asthma in mouse

Objective(s):Bone marrow-derived mesenchymal stem cells (BMSCs) have attracted significant interest to treat asthma and its complication. In this study, the effects of BMSCs on lung pathology and inflammation in an ovalbumin-induced asthma model in mouse were examined. Materials and Methods:BALB/c mice were divided into three groups: control group (animals were not sensitized), asthma group (an...

Biological behaviors of muscarinic receptors in mesenchymal stem cells derived from human placenta and bone marrow

Objective(s): Cells perform their functional activities by communicating with each other through endogenous substances and receptors. Post-translation, stem cells function properly in new host tissue by carrying specific cell surface receptors. We aimed to characterize muscarinic receptor subtypes in mesenchymal stem cells (MSCs) together with osteogenic and adipogenic...
