from comparative studies of five breast carcinoma lines ( bt20 , bt549 , mcf-7 , t47d , and zr75-1 ) , as well as an epithelial line established from milk ( hbl-100 ) , we report the stimulation of expression of ma5-reactive antigen in a mucinous breast tumor cell line ( bt549 ) through the use of a culture medium supplemented with charcoal-absorbed fetal calf serum , insulin , and hydrocortisone .
