objective(s):the limited homing potential of bone-marrow-derived mesenchymal stem cells (bm-msc) is the key obstacle in msc-based therapy. it is believed that chemokines and chemokine receptor interactions play key roles in cellular processes associated with migration. meanwhile, mscs express a low level of distinct chemokine receptors and they even lose these receptors on their surface after a...

Clinical applications of mesenchymal stem cells (MSCs) rely on their capacity to home and engraft in the appropriate target tissues for a long time. Homing and engraftment capacity of these stem cells depend on the expression of Chemokines and their receptors. Ex vivo expanded MSCs exhibit homing potential when grafted to injury tissue but their homing efficiency has been observed very poor bec...

It has been reported that CXCL12 binding to CXCR4 induces several intracellular signaling pathways, and enhances survival, proliferation, and migration of malignant cells. Herein we examined the effects of anti-estrogen tamoxifen and anti-allergic tranilast drugs as a single or in combination on invasion by two in vitro invasion assays, wound-healing and matrigel invasion on MCF-7 and MDA-MB-23...

Objective(s): Cord blood (CB) is known as a valuable source of hematopoietic stem cells (HSC). Identifying strategies that enhance expansion and maintain engraftment and homing capacity of HSCs can improve transplant efficiency. In this study, we examined different culture conditions on ex vivo expansion and homing capacity of CB-HSCs. Materials and Methods: In this study, 4-5 different units o...

background: metastasis is one the most leading cause of death from cancer. the chemokine receptor of cxcr4 has an important role in cell migration and cancer metastasis. additionally, metastasis is always associated with the process of epithelial-mesenchymal transition (emt). in this study the correlation between expression of cxcr4 and emt-tfs has been examined. methods: the expression of cxcr...

normal 0 false false false en-us x-none ar-sa background: prostate cancer is one of the most common cancer types both in western and eastern countries, involving mostly elder men. the mechanisms underlying the prostate cancer development remain unclear. prostate-specific antigen (psa) is the only well accepted marker for prostate cancer diagnosis and prognosis. the diagnosis and treatment of pr...

OBJECTIVES Experimental myocardial infarction triggers secretion of Stromal cell-derived factor1 and lead to increase in the expression of its receptor "CXCR4" on the surface of various cells. The aim of this study was to evaluate the expression pattern of CXCR4 in peripheral blood cells following time-course permanent and temporary ischemia in rats. MATERIALS AND METHODS Fourteen male Wistar...

Abstract Placental dysfunction originates during placental development, specifically the events of placentation. Vascularization is a key component placentation due to its role in fetal-maternal exchange. Cytokines are regulators development; signaling chemokine ligand 12 (CXCL12) and receptor (CXCR4) drives vascularization. Utilizing an vivo sheep model, we demonstrated that suppressing CXCL12...
