Two of the signature genetic events that occur in human gliomas, EGFR amplification and IDH mutation, are poorly represented in experimental models in vitro. EGFR amplification, for example, occurs in 40 to 50% of GBM, and yet, EGFR amplification is rarely preserved in cell cultures derived from human tumors. To analyze the fate of EGFR amplified and IDH mutated cells in culture, we followed th...

Primary chondrocytes dedifferentiate in serial monolayer with respect to their morphological and biosynthetic phenotype. They change from a round to a flattened fibroblast-like shape, and collagen I is secreted instead of the cartilage-specific collagen II. We analysed in detail the time course of dedifferentiation of mature bovine articular chondrocytes in monolayer for up to 32 weeks. Assessm...

Buffalo ovaries were collected from a slaughter house and cumulus cells oocytes complexes (COCs) were recovered for preparation of 2-D, 4-D, 6-D and 8-D monolayer. Cumulus cells were stripped off by repeated pipetting into TCM-199 medium supplemented with 10% FCS. Approximately 2x106/ml cumulus cell were transferred in 100 μl drops of culture medium and incubated in humidifi ed atmosphere of 5%...

In this study, five carp pituitary glands were collected and dispersed enzymatically and mechanically.Then, the cells were cultivated as monolayer in MEM (minimum essential medium Eagle). The culture mediawere collected after 72 h and frozen at -20°C. Carp ovarian follicles also were separated mechanically andincubated in BSS (basic salt solution) Cortland medium in 24-well microplates for 48 h...

background: radiotherapy is an established therapeutic modality for prostate cancer. resveratrol, a natural antioxidant, has been shown to inhibit carcinogenesis and to block the process of tumor initiation and progression. no data is available on the response of cellular spheroid to reseveratol. in this study we have examined the effect of resveratol on the radiation response of human prostate...

Ex vivo expansion of human umbilical cord blood cells (HUCBC) is explored by several investigators to enhance the repopulating potential of HUCBC. The proliferation and expansion of human hematopoietic stem cells (HSC) in ex vivo culture was examined with the goal of generating a suitable clinical protocol for expanding HSC for patient transplantation. Using primary human mesenchymal stem ...

The cytotoxic effects of volatile and water-insoluble organic solvents (ethylbenzene, tetrachloroethylene, n-hexane) were tested on isolated hepatocytes in monolayer culture by using the 3-(4,5 dimethylthiazol-2-yl)-2,5 diphenyltetrazolium bromide (MTT) reduction assay. All of the tested compounds inhibited metabolic activity of hepatocytes and this effect depended on the concentration of solve...

ZR-75-1 human mammary cancer cells can be grown in serum-free medium in an estradiol- and tamoxifen-sensitive manner. Growth occurs both in monolayer and suspension culture, although serum is necessary during the initial plating of the cells in monolayer culture. Optimal stimulation of proliferation by estradiol occurs at 10(-8) and 10(-9) M. Tamoxifen alone weakly stimulated growth in a dose-d...

A previous publication documented a sarcomatous transformation observed in cell line derived from rat lymphoma growing monolayer culture. (9) The morphological and cytogenetic changes found, suggested the presence of virus differentiation malignant lymphoblasts toward histiocytes present paper describes, under electron microscope structural features original tumor, cells culture sarcoma. This s...

ZR-75-1 human mammary cancer cells can be grown in serumfree medium in an estradiciand tamoxifen-sensitive manner. Growth occurs both in monolayer and suspension culture, al though serum is necessary during the initial plating of the cells in monolayer culture. Optimal stimulation of proliferation by estradiol occurs at 10~8 and 10~9 M. Tamoxifen alone weakly stimulated growth in a dose-depende...
