[ 1 ] - Immunomodulatory Effect of Mesenchymal Stem Cells in Multiple Sclerosis and Experimental Autoimmune Encephalomyelitis: A Review Study
Multiple Sclerosis (MS) is a chronic inflammatory and demyelinating disease of the central nervous system that may lead to disability of the patient. Current MS treatment regimens are still insufficient and research is conducted for developing more effective therapies capable of targeting neurodegeneration, inflammation, and demyelination. Recent results of experimental and clinical studies in ...
[ 2 ] - جداسازی و تعیین خصوصیات اگزوزوم های جدا شده از سلول های بنیادی مزانشیم با استفاده از روش اولترا سانتریفیوژ
Abstract Background and Aim: In recent years, Mesenchymal stem cell functions have been at the center of attention of researchers. Evidence shows that Mesenchymal stem cells act as paracrine manner and thus, biological agents such as exosomes and soluble factors are present in the supernatant that can act as same as Mesenchymal stem cells. Therefore, isolating exosomes from mesenchymal stem ce...
[ 3 ] - Exosomes: Mediators of Immune Regulation
Extracellular Vesicles, including exosomes, are small membrane fragments released from many cell types, like Mesenchymal Stem Cells (MSCs). They were recognized as a mechanism of intercellular communication. They can transfer proteins, lipids and nucleic acids to other cells. Thus, they have many physiological (angiogenesis, coagulation and tissue repair, etc.) and pathological (e.g. in autoimm...
[ 4 ] - The Effects of Dental Pulp Stem Cell Conditioned Media on the Proliferation of Peripheral Blood Mononuclear Cells
Background: Dental Pulp Stem Cells (DPSCs) are multipotent mesenchymal stem cells. DPSCs can renew themselves and differentiate into various cell types such as adipocytes, osteocytes, neurons, etc. DPSCs possess immunomodulatory properties and can inhibit peripheral blood mononuclear cell (PBMC) proliferation. Recent studies showed that conditioned-medium mesenchymal stem cells also had immunos...
[ 5 ] - Application of extracellular vesicles in the treatment of inflammatory bowel disease
Introduction: Inflammatory bowel disease(IBD) is caused by genetic, environmental, microbial and immune factors. IBD has two primary forms: Ulcerative colitis and Crohn´s disease. The incidence of IBD has significantly increased over the last few decades. Given that patients have poor response to drug treatments or are resistant to drug therapies, new therapies are needed for gastrointestinal i...
[ 6 ] - Neutrophils to Lymphocytes Ratio and the Prognosisof the COVID-19 Patients
Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) is a new pandemic virus, a global concern, and has threatened human health. This virus binds to the Angiotensin-Converting Enzyme 2 (ACE2) that is expressed on different cells, especially on the alveolar cells. So the virus can enter the lung cells and causes respiratory syndromes. In Coronavirus Disease 2019 (COVID-19) that is cause...
[ 7 ] - A New Approach to Monitoring and Evaluation of Cecal Ligation and Puncture Sepsis Model
Background: Sepsis is a systemic inflammatory disease in response to the pathogens that leads to vital organ failures the failure of vital organs. Appropriate animal models should be developed to measure the effectiveness of therapeutic methods. Cecal Ligation and Puncture (CLP) is the most widely used methods of creating the sepsis model. Some variables interfere in the creation of the CLP mod...
[ 8 ] - Role of mesenchymal stem cells in growth and progression of cancer and prospective potentials in cancer therapy
Introduction: Mesenchymal stem cells (MSCs) are present in most tissues of the body. These cells are involved in various biological processes, such as maintaining tissue homeostasis and wound healing. Recent studies have shown that tumor associated MSCs (TA-MSCs) are also present in tumor microenvironment (TME) of most solid tumors. MSCs have a strong tendency to migration toward tumor tissues....
