Immunofluorescent studies of cultured canine tumor cells
International Journal of Cancer, 1972AbstractThe indirect immunofluorescent (IF) test was used in an immunological survey of 17 sera from tumor‐bearing and normal dogs. These sera were reacted against 33 cultured canine tumor and normal cells. A high percentage (70%) of IF positive reactions were seen in cells derived from sarcomatous tumors while only 4% of the cultures from tumor types ...

Entosis and Cell Cycle in Tumor Cell Culture
Cell and Tissue Biology, 2019Entosis is a type of cell cannibalism during which one tumor cell invades another. The fate of the inner cell can vary. It can leave the entotic vacuole, divide within it, or be subjected to lysosome-mediated degradation. The aim of our work was to determine whether MCF7 (p53+) human breast adenocarcinoma cells and A431 (p53-) human epidermoid ...

Effect of a hypoxic tumor cell cytotoxic disulfide on the membrane and DNA of tumor cells in culture
Anti-Cancer Drugs, 1992A disulfide, n-butyl 2-imidazolyl disulfide (III-2), recently reported to be more toxic to EMT6 tumor cells under hypoxia has also been shown to be preferentially toxic to KHT/iv cells under hypoxia with an IC90 value 3-fold lower versus that measured in air. The IC90 values for both cell lines were markedly affected when the pHe was decreased.

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.

1995
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

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.

Influence of in Vitro Culture Conditions on Tumor Cell Differentiation
Tumori Journal, 1986We studied the influence of different in vitro culture conditions on the growth characteristics of certain human and murine tumor cell lines maintained in either conventional medium supplemented with FCS or in serum-free synthetic medium. A lower growth rate was observed for all of the cell lines maintained in serum-free conditions.

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.

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.
