Objective(s): This paper aims to investigate synergistic inhibition of polysaccharide from Sepia esculenta ink (SIP), a newly isolated marine polysaccharide in our laboratory, on breast cancer MDA-MB-231 cells exposed to cisplatin. Materials and Methods: Cell viability of MDA-MB-231 cells was determined by CCK 8 assay. Median-effect concentration was analyzed using Chou-Talalay method that was ...

Background: Dental Pulp Stem Cells (DPSCs) are multipotent mesenchymal stem cells. DPSCs can renew themselves and differentiate into various cell types such as adipocytes, osteocytes, neurons, etc. DPSCs possess immunomodulatory properties and can inhibit peripheral blood mononuclear cell (PBMC) proliferation. Recent studies showed that conditioned-medium mesenchymal stem cells also had immunos...

Objective(s): To reveal the detailed mechanism underlying the functions of salidroside on the inflammation of intestinal epithelial cells during IBD.Materials and Methods: Quantitative real-time PCR was employed to assess the expression of IL-6, IL-10, and α-defensins 5 and 6. ELISA assay was performed to measure the secretion of IL-6 and IL-10. MTT assay was used to determine the cell viabilit...

In this in vitro study, T cell responses induced by breast tumor cell lysate pulsed monocyte-derived DCs were analyzed in terms of proliferation, specific cytotoxicity and cytokine-release in order to use in immunotherapeutic settings. Nylon wool enriched T lymphocytes from 5 patients with breast cancer stimulated in vitro with tumor cell lysate pulsed monocyte-derived DCs and their proliferati...

objective: we introduce an rgd (arg-gly-asp)-containing peptide of collagen iv origin that possesses potent cell adhesion and proliferation properties. materials and methods: in this experimental study, the peptide was immobilized on an electrospun nanofibrous polycaprolactone/gelatin (pcl/gel) hybrid scaffold by a chemical bonding approach to improve cell adhesion properties of the scaffold. a...

conclusions our data suggest that preconditioning with 5 μm h2o2 + 0.5% fbs and 10 μm h2o2 + 5% fbs improved cell proliferation and viability. however, the mechanisms related to protective properties of preconditioning and using this strategy in stem cell therapy requires more research. background mesenchymal stem cells (mscs) survival decreased following in vivo injection and its application h...
