ABSTRACT

Morphological, caryological, cytoproliferative, and isoenzyme studies of Syrian hamster cells HTC-2 and HTC-1 transformed by herpes simplex virus type 2 and a HTCT line of tumor cells were carried out. The hamster origin of these cell lines was established by chromosomal analysis and electrophoretic mobility of lactate dehydrogenase and glucose-6-phosphate-dehydrogenase isoenzymes. The transformed and tumor cell lines differ from normal cells by altered morphology, an aneuploid chromosome set and increased proliferative activity. Electron microscopic examination of transformed cells revealed increased amounts of filamentous and tubular structures in the cytoplasm. No retroviruses were found.
