title: A comparative study of four sublines of mouse fibroblast cells.
abstract: Cell doubling time, DNA distribution pattern, frequency distribution of chromosome numbers per cell and degree of synchrony obtained after mitotic selection were studied in 4 different sublines of mouse fibroblast cells, NCTC L-929, in culture. The 4 sublines did not differ with respect to their cell kinetic data but showed changes of the chromosome pattern compared to the stemline and compared to each other suggesting that chromosome analysis provides a very sensitive means to detect evolutianary changes of a permanent cell line.
