BACKGROUND AND AIM: Oral lichen planus (OLP) is a chronic, autoimmune, inflammatory disease. The progression of OLP to oral squamous cell carcinoma (OSCC) has generated a longstanding controversy about the details of this malignant transformation potential. This study aimed to do a systematic review on the molecular markers related to the malignant transformation of OLP.METHODS: We searched the...

Introduction: Bone marrow (BM) is a known source of mesenchymal stem cells (MSCs) that are used for cell therapy. This study attempts to identify if the Wharton’s Jelly (WJ) is a suitable substitute for BM as a source for MSCs. Materials and Methods: A population of human WJ and BM stem cells were isolated and incubated with fluorescein conjugated antibodies for five specific MSC markers....

Background and Objective: Mesenchymal stem cells (MSCs) promote metastasis in colorectal cancer; however, the mechanism underlying this process is not fully understood. Epithelial to mesenchymal transition (EMT) is a key step in tumor acquisition of metastatic phenotype. We aimed to investigate the effect of MSCs on the expression of EMT markers, as well as cancer stem cell markers in HT-29 col...

objective: endothelial progenitor cells (epcs) have a potential application for cell therapy, however, their biological nature is not well-understood. epcs also possess some stemness features, such as their clonogenicity and differentiation capacity. the main aim of this study was to evaluate the expression of certain transcription factors regulating self-renewal property of stem cells. materia...

Objective(s): In the past few decades, variety of foetal, embryonic and adult stem and progenitor cells have been tried with conflicting outcome for cell therapy of central nervous system injury and diseases. Cellular characteristics and functional plasticity of Globose basal stem cells (GBCs) residing in the olfactory epithelium of rat olfactory mucosa have not been studied in the past by the ...

activated macrophages have been classified into classical (m1) and alternative (m2) macrophages. we aimed to establish a method to yield enough number of macrophages to analyze their molecular, biological and immunological functions. we used drugs; adjuvant albumin from chicken egg whites—imject alum (ova- alum) and ova complete freund adjuvant (ova-cfa), to induce macrophages to m2 and m1 resp...

Objective(s):Mesenchymal stem cells (MSCs) derived from Wharton’s jelly (WJ-MSCs) are now much more appealing for cell-based infertility therapy. Hence, WJ-MSCs differentiation toward germ layer cells for cell therapy purposes is currently under intensive study. Materials and Methods: MSCs were isolated from human Wharton’s jelly and treated with BMP4, retinoic acid (RA) or co-cultured on huma...

objective(s) bone marrow is the traditional source of human multipotent mesenchymal stem cells (mscs), but adipose tissue appears to be an alternative and more readily available source. in this study, rat adipose-derived stem cells (adscs) were induced to differentiate into schwann-like cells and compared with rat bone marrow stem cells (bmscs) for their schwann-like cells differentiation poten...

background: recent publications about differentiation of stem cells to germ cells have motivated researchers to make new approaches to infertility. in vitro production of germ cells improves understanding differentiation process of male and female germ cells. due to the problem of using embryonic stem cells (esc), it’s necessary the mentioned cells be replaced with some adult multi-potent stem ...

purpose: to separate and characterize orbital fat-derived stem cells (ofscs) and compare its cellular and molecular properties with those of bone marrow-derived mesenchymal stem cells (mscs) and adipose-derived stem cells (ascs). methods: stem cells from orbital fat, abdominal fat and bone marrow aspirates have been isolated. we assessed stem cell specific cell surface markers using cytometry, ...
