Malignant mesothelioma is an aggressive tumor arising from mesothelial cells of serous membranes, and forms spheroid-like cell aggregates in pleural and peritoneal effusions. We examined the levels of anoikis, apoptosis induced by the detachment of cells from the extracellur matrix, in suspension culture in the human mesothelioma cell line NCI-H2052. NCI-H2052 cells were adherent in conventiona...
The expression of cytokeratins and vimentin was investigated in Madin-Darby bovine epithelial cells (MDBK) in culture under conditions of varied cell spreading and cell-cell contact. When extensive cell-cell contact was achieved by seeding cells at high density in monolayer, or in suspension culture in which multicellular aggregates formed, the cells synthesized high levels of cytokeratins and ...
The effect of serum on cell growth and monoclonal antibody (MAb) productivity was studied in a repeated fedbatch mode using both free-suspended and immobilized S3H5/gamma2bA2 hybridoma cells. In the suspension culture, serum influenced the cell growth rate but not the specific MAb productivity. The average specific growth rate of the suspension culture in medium containing 10% serum was approxi...
Introduction: There is a fast growing tendency in the consumption of herbal remedies in the developing countries. One of the traditional medicines used for male infertility is Date palm (Phoenix dactylifera) pollen (DPP). The goal of the present study was to investigate the effect of aqueous extract of DPP on In vitro viability and proliferation rate of neonate mouse spermatogonial stem cells (...
Growing insect cells with high air space in culture vessel is common from the early development of suspension cell culture. We believed and followed it with the hope that it allows sufficient air for optimal cell growth. However, we missed to identify how much air exactly cells need for its growth and multiplication. Here we present the innovative method that changed the way we run insect cell ...
Extended Abstract Introduction and Objective: In order to overcome the contamination problems, as well as the usual method of increasing potato through micro tuber, micropropagation has been considered through tissue culture. The aim of this study was to evaluate the callus induction and embryogenesis in potato cultivars using leaf explants. Material and Methods: For this purpose, micropropa...
Objective(s):P In vitro chemosensitivity and resistance assays (CSRAs) are a promising tool for personalized treatment of glioblastoma multiform (GBM). These assays require a minimum of 1 to 2 g of tumor specimen for testing, but this amount is not always accessible. We aimed to assess the feasibility and validity of utilizing stereotactic biopsies of GBM in CSRAs. Materials and Methods: Single...
Woodland sage (Salvia nemorosa) is an important native medicinal plant in Iran and is considered as a rich source of phenolic and flavonoids compounds. The present research was conducted with respect to the optimization of medium for biomass accumulation and secondary metabolite production in cell suspension culture of S. nemorosa. In this research the effects of total nitrogen content (0, 15, ...
