Objective Aspirated ovarian follicular fluids (FF) contain luteal granulosa cells (LGC) and other contaminating cell types. Several strategies such as the antibody binding methods, the flask method, the cell strainer, and the positive selection of granulosa aggregates after density gradient centrifugation, were tested as LGCs purification methods. Each of these strategies has its own advantages...

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...

stem cells are of great interest for regenerating disturbed tissues and organs. these cells are commonly isolated from the bone marrow, but there has been interest in other tissues in the recent years. in this study, we evaluated the possibility of isolation of stem cells from oral connective tissue and investigated their characteristics.in this experimental study, sampling from the bone marrow...

Objective- To evaluate growth characteristics and differentiation capacity of equine mesenchymal stem cell (eMSCs) derived from bone marrow (BM). Study design- In vitro experimental study. Animals- Four young adult horses (2-5 years old) Procedure- Cell morphology and growth characteristics of eMSCs harvested from BM were evaluated in standard culture conditions. eMSCs in passage 3 were subj...

background: one area of nanoscience deals with nanoscopic interactions between nanostructured materials and biological systems. to elucidate the effects of the substrate surface morphology and viscoelasticity on cell proliferation, fractal analysis was performed on endothelial cells cultured on nanocomposite samples based on silicone rubber (sr) and various concentrations of organomodified nano...

background: our previous studies revealed an inhibitory effect of icd-85 (venom derived peptides) on mda-mb231 and hl-60 cell lines, through induction of apoptosis. the purpose of this study was to investigate apoptosis-induced mechanism on hela and mrc-5 cells by icd-85 through activation of caspase-8. methods: cell viability, cytosolic enzyme lactate dehydrogenase (ldh) and cell morphology we...

Background & objective: The histologic distinction of small cell from non-small cell lung carcinoma and correct identification of all subtypes of lung carcinoma are very important in treatment management. The main method for histologic classification of lung tumors is based on morphology. However, in small bronchoscopic biopsies in par...
