โœฆ Synopsis


Abstract

Rat embryo cells subjected in vitro to transient incubation at an elevated temperature (39ยฐ C) became transformed and induced fibrosarcomas in both homologous and heterologous hosts. Malignant transformation correlated with the occurrence of karyotypic changes which appeared long after incubation at 39ยฐ C and subsequent return to 37ยฐ C. Control cultures incubated at only 37ยฐ C did not show similar chromosomal changes or induce tumors and remained predominantly diploid during the same observation period. In contrast to rat embryo cells, marmoset monkey cell cultures incubated at 39ยฐ C did not develop characteristics of transformed cells.
