Abstract
DU4475 is a new human breast cell line derived from a cutaneous metastatic nodule from a patient with advanced breast cancer. It has been in continuous culture for more than 1 yr and has survived 140 subcultivations. The cells grow in suspension, displaying clusters and free-floating aggregates with serpentine-like outgrowths. The cell line is hypotetraploid with modal chromosome numbers between 86 and 93 and possesses 5 to 6 distinctive marker chromosomes. The cells grow readily in athymic nude mice and produce tumors from which cells can be reintroduced to culture in vitro.
