Relationship of cell growth behavior in vitro to tumorigenicity in athymic nude mice. 1976

C D Stiles, and W Desmond, and L M Chuman, and G Sato, and M H Saier

The serum requirements, anchorage requirements, saturation densities, and contact inhibition responses of a variety of mammalian cell lines were determined under uniform conditions. The serum requirement of both transformed and normal cells was a sensitive function of initial plating density. Cloning efficiency on irradiated mouse monolayers was found to be an invalid indicator of contact inhibition of growth, since most cell lines that failed to form visible colonies on cell monolayers nonetheless proliferated on these monolayers. When normal and neoplastic cells from a variety of sources were examined, none of the growth parameters that serve to define the transformed state in vitro correlated consistently with cellular tumorigenicity in athymic nude mice. It is concluded that the most reliable and physiologically meaningful assay for malignant transformation is, at present, cellular tumorigenicity in athymic nude mice.

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.

D013950	Thymus Gland	A single, unpaired primary lymphoid organ situated in the MEDIASTINUM, extending superiorly into the neck to the lower edge of the THYROID GLAND and inferiorly to the fourth costal cartilage. It is necessary for normal development of immunologic function early in life. By puberty, it begins to involute and much of the tissue is replaced by fat.
