Publisher Summary This chapter describes generally successful methods for culture initiation of tumor cells from multiple human and animal source tissues. The success rate of 80-90% for the initiation of viable primary cultures with the propensity to maintain the ability to divide and differentiate for at least two to three subcultures (which is 4-10

Transformation of Cells in Human Bone Tumor Cultures
2015Two cell lines from tumors of 16 patients with osteosarcoma and two cell lines from 5 patients with giant cell tumor of bone showed conversion of cell type after 2 to 13 months in culture. Transformed cells of epithelial like morphology appeared in small focal areas and rapidly overgrew nontransformed cells.

On the growth and stability of cell cultures and solid tumors
Journal of Theoretical Biology, 1976A theory is formulated to describe the growth and movement of certain cell cultures and solid tumors in response to an arbitrary distribution of nutrient. Conditions are established for the unstable development of a colony in which internal pressure forces overcome surface tension and adhesion.

Study of the motility and contractility of cultured brain-tumor cells [PDF]
Journal of Neurosurgery, 1985 ✓ The motility of cultured cells and contractility of their cytoplasmic microfilament system were studied in benign compared with malignant brain-tumor cells. Motility of cultured cells was continuously monitored in a perfusion chamber by a computerized microscope system equipped with an autotracking device.

Influence of interferon on adriamycin uptake of cultured tumor cells
International Journal of Cancer, 1989AbstractEffect of human interferon β (IFNβ) or interferon γ (IFNγ) on cellular uptake of adriamycin (ADM) was measured in 3 in vitro‐cultured human tumor cell lines. Pre‐incubation of tumor cells with 100 lU/ml of IFNβ or γ for 6 hr resulted in an increased intracellular ADM concentration, but ADM efflux was not affected by the IFNs.

Tumor promoters: Effects on proliferation and differentiation of cells in culture
Life Sciences, 1978Abstract Tumor promoters enhance tumor formation when administered after an initiating action by a carcinogen. The phorbol diester class of tumor promoters has been shown to affect many biochemical and biological processes in mouse skin and cell culture.

Adrenocorticotropin-induced unresponsiveness in cultured adrenal tumor cells
Biochimica et Biophysica Acta (BBA) - General Subjects, 1978Our results demonstrate that adrenocorticotropin (ACTH)-induced refractoriness occurs in cultured adrenal tumor cells. Cells became 85% refractory to ACTH-induced cyclic AMP formation in 20 min and the effect persisted if the hormone remained in the incubation medium.

Effect of glycosaminoglycans on the growth of cultured tumor cells.
Journal of Osaka Dental University, 1993The effect of various glycosaminoglycans on the growth of cultured Tawa sarcoma cells (CTS cells) were determined under both fast and slow growth conditions. Hyaluronic acid, chondroitin, chondroitin 4-sulfate, and chondroitin 6-sulfate (all of which have only one type of uronic acid, glucuronic acid) inhibited the growth of CTS cells during fast ...

Carbonic Anhydrases in Mammalian Cell Culture and Tumors
1991This chapter describes some of the work that has been performed with tissue culture cells to understand how carbonic anhydrase (CA) is regulated in various cell types. The advantages of studying genes and gene products in tissue culture are that the treatments of the cells can be completely defined and, in many cases, homogeneous populations of cells ...
