Description
Established from the local metastatic cutaneous nodule of an undifferentiated carcinoma of a 62-year-old woman which developped seven years after radical mastectomy of a poorly differentiated ductal carcinoma of the breast; cells were described to grow readily in athymic nude mice and to produce tumors from which cells could be introduced into culture in vitro; cells reportedly express components of milk fat globules and the BCL1 gene
