Inhibition of the growth of murine tumour cells in vitro by serum from non-immune syngeneic and allogeneic mice. 1978

G Ablett, and C Bishop, and J W Sheridan, and K J Donald

Sera from DBA/2 and Quackenbush mice (which are non-immune for mastocytoma and Sarcoma 180 respectively) contain a heat-labile (56 degrees for 30 min) component(s) that inhibits the in vitro growth of DBA Mastocytoma P-815 X-2 and Sarcoma 180. Adsorption of the sera with tumour cells at 4 degrees did not eliminate the factor(s), suggesting that it is not an antibody. In liquid suspension cultures inhibitory activity was observed at concentrations of mouse serum of 10--20% and in semisolid agar clonogenic cell assays at concentrations as low as 1%. The influences of the inhibitor(s) for both tumours and in both culture systems were parallel. However, there was a quantitative difference in susceptibility to other environmental factors (FCS concentration, bicarbonate concentration, and O2 tension) between the two tumours. These results parallel the in vivo findings where intravenously injected mastocytoma cells produced more tumours than did Sarcoma 180.

D003470	Culture Media	Any liquid or solid preparation made specifically for the growth, storage, or transport of microorganisms or other types of cells. The variety of media that exist allow for the culturing of specific microorganisms and cell types, such as differential media, selective media, test media, and defined media. Solid media consist of liquid media that have been solidified with an agent such as AGAR or GELATIN.	Media, Culture

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D001639	Bicarbonates	Inorganic salts that contain the -HCO3 radical. They are an important factor in determining the pH of the blood and the concentration of bicarbonate ions is regulated by the kidney. Levels in the blood are an index of the alkali reserve or buffering capacity.
