title: A new cell line from a human chondrosarcoma.
abstract: Morphological and growth characteristics are described of a rapidly growing cell line with epithelioid and giant-cell characteristics derived from a chondrosarcoma in a male patient 65 years of age. This cell line is of considerable interest because in these cells cross-reacting antigens with known animal oncorna-viruses are present. Biochemically, the cells contain particles with a density of 1-16 with "cores" of density 1'23 associated with a reverse-transcriptase-like enzyme and with 70S RNA. Occasionally, virus-like particles were demonstrated by electron microscope in material derived from the culture medium.
