background: mesenchymal stem cells (mscs) with their potential to differentiate into mesodermal and non-mesodermal lineages have several immunomodulatory characteris-tics. these properties make them promising tools in cell and gene therapy. objective: to evaluate the potential therapeutic applications of autologous msc in improving clinical manifestations of ms patients. methods: ten patients w...

stem cells are undifferentiated cells with the ability of proliferation, regeneration, conversion to differentiated cells and producing various tissues. stem cells are divided into two categories of embryonic and adult. in another categorization stem cells are divided to totipotent, multipotent and unipotent cells. so far usage of stem cells in treatment of various blood diseases has been studi...

low-intensity laser therapy (lilt) is defined to supply direct biostimulative light energy to the cells. while several studies have demonstrated that lilt has stimulating effects on bone cells and can accelerate the repair process of the bone, others reported delayed fracture healing or no effects after lilt. the aim of this article was to review the studies evaluating the biomodulation effects...

spinal cord injury (sci) is a debilitating disease which leads to progressive functional damages. because of limited axonal regeneration in the central nervous system, there is no or little recovery expected in the patients. different cellular and molecular approaches were investigated in sci animal models. cellular transplantation of stem cells can potentially replace damaged tissue and provid...

INTRODUCTION: Triple negative cancer is one of the most aggressive subtypes breast cancer. Currently, no effective treatment methods have been proposed that would significantly affect long-term results treatment. OBJECTIVE: To summarize possibilities theranostics and nanteranostics in visualization elimination malignant cells immunosuppressive microenvironment thriple MATERIALS AND METHODS: A s...

carcinogenesis is a multistep process characterized by the gradual accumulation of genetic changes that ultimately lead to cancer. these genetic mutations can impart limitless replicative potential to the cancer cells making them immortal. telomeres are repeat nucleotide sequence ttaggg that are present at the end of chromosomes. its functions are to protect the chromosomal ends and to ensure t...

Objective(s):The colorectal cancer stem cells (CSCs) with the CD133+ phenotype are a rare fraction of cancer cells with the ability of self-renewal, unlimited proliferation and resistance to treatment. Quercetin has anticancer effects with the advantage of exhibiting low side effects. Therefore, we evaluated the anticancer effects of quercetin and doxorubicin (Dox) in HT29 cancer cells and its ...

Objective(s):Mesenchymal stem cells (MSC) can be isolated from adult tissues such as adipose tissue and other sources. Among these sources, adipose tissue (because of easy access) and placenta (due to its immunomodulatory properties, in addition to other useful properties), have attracted more attention in terms of research. The isolation and comparison of MSC from these two sources provides a ...
