Ovarian cancer is the most frequent cause of gynecologic malignancies associated death. Primary or acquired cisplatin resistance frequently occurred during ovarian therapy. Cancer stem cells (CSC) tend to form minimal residual disease after chemotherapy and are implicated in relapse. The ability reprogram their metabolism has recently been related with maintenance CSC chemotherapies. current st...

background : cancer stem cells are a subgroup of tumor cells that have the capability for self-renewal and differentiation and are characterized by multiple markers. several studies have been conducted to identify these cells in colorectal cancer, including stem cell marker cd24. this study has evaluatedtheassociation of cd24 expression with clinicopathologic features and survival in an immunoh...

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...

OBJECTIVE Aldehyde dehydrogenase (ALDH) expressing cells have been characterized as possessing stem cell-like properties. We evaluated ALDH+ ovarian cancer stem cell-like properties and their role in platinum resistance. METHODS Isogenic ovarian cancer cell lines for platinum sensitivity (A2780) and platinum resistant (A2780/CP70) as well as ascites from ovarian cancer patients were analyzed ...

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...

Objective Chemotherapy may damage ovaries. L-carnitine (LC) as a type of flavonoid antioxidants and bone marrow stromal cells (BMSCs) as a type of mesenchymal stem cells may recover damaged ovaries. It seems that LC has favorable effects on differentiation, increasing lifespan and decreasing apoptosis in BMSCs. The aim of this study was to investigate the effects of co-administration of BMSCs a...

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...

chronic myeloid leukemia (cml) is a myeloproliferative disease of the hematopoietic stem cells, characterized by the presence of the philadelphia (ph) chromosome. although imatinib inhibits the bcr-abl kinase activity, clinical experiences confirm that imatinib may not target cml stem cells in vivo. the identification of signaling pathways responsible for the self-renewal properties of leukemic...

helicobacter pylori was the main cause of gastric cancer (gc) in all over the world that results in intestinal- and diffuse-type carcinoma. infection by this bacterium remains chronic for a long time. in vitro studies have highlighted the role of stem cells in gc. h. pylori infection results in tissue injury and the adult/tissue stem cells subsequently start to replace the dead cells. the genet...

Cancer stem cells or tumor-initiating cells (CSC/TICs), which can undergo self-renewal and differentiation, are thought to play critical roles in tumorigenesis, therapy resistance, tumor recurrence and metastasis. Tumor recurrence and chemoresistance are major causes of poor survival rates of ovarian cancer patients, which may be due in part to the existence of CSC/TICs. Therefore, elucidating ...
