Abstract
Some major transformation related biological and growth properties have been analysed in an in vitro, system to characterize the PMM-14 cell line, a 20-methylcholanthrene induced transformed mouse embryonic fibroblast cell line. The population doubling time of this cell line was 19 h with moderately high saturation density and plating efficiency. Attachment detachment properties showed reduced adhesion to substratum. Cytogenetic study revealed the existence of a large number of Robertsonian biarmed chromosomes with hypertriploid modal range (60-69) represented by about 21% cells. These cells showed enhanced concanavalin A agglutinability which was reduced by trypsin treatment. Its neoplastic nature was finally established by its ability to grow in agar with a high plating efficiency.
