✦ Synopsis

We investigated whether the metastatic potential of various t u p o r cell lines was related to chromosome counts or t o rate of growth in vitro or in vivo. Clones of known metastatic potential derived from a C3H-fibrosarcoma induced by UV radiation (UV-2237) and from C57BL/6 B16 melanoma were tested for these characteristics. N o correlation was found between the growth rate of these clones in monolayer culture or at a subcutaneous site and their ability to produce metastases. The cells from clones of UV-2237 were mainly in the diploid range with only one exception, and the B16 clones were all hyperploid. Thus, there was also no correlation between malignant behavior of the clones and gross changes in chromosome number.
