Abstract:
The properties of a new cell line derived from a human retroperitoneal liposarcoma are described. The cells do not grow at low cell concentrations and contain in their cytoplasm large numbers of droplets that stain with Oil Red O. No indication of the presence of endogenous virus particles could be found. The mean chromosome number per cell is 36, with several constant markers, the most conspicuous of which is a large submetacentric marker due to a translocation between chromosomes 4 and 11, which is present in every cell. The liposarcoma cells show an enhanced uptake of [14C]acetate compared to normal human fibroblasts.
