“…Over the years, new cell lines have been established from only a very small percentage of primary tumours (1-2%; Petersen et al, 1990;Band et al, 1990;Meltzer et al, 1991). However, a more recent report has described the long-term culture of approximately 7% of cultures established from primary breast cancers, nearly all of which went on to form new cell lines (McCallum and Lowther, 1996). Interestingly, the majority of these cultures grew in suspension, in contrast to most other studies, and were more likely to be established from grade III tumours with a steroid receptor-negative phenotype (McCallum and Lowther, 1996).…”

Summary As experimental models for breast cancer, most studies rely on established human breast cancer cell lines. However, many of these lines were established over 20 years ago, many from pleural effusions rather than the primary tumour, so the validity of using them as representative models is questionable. This paper describes our experiences, over a 3-year period, in establishing short-term epithelial-cellenriched preparations from primary breast tumours based on differential centrifugation followed by culture in selective media. Epithelial cells were successfully cultured from 55% of samples, but culture success did not appear to be correlated with tumour histology, stage, grade or node status. Epithelial cell-enriched cultures were immunopositive for broad-spectrum cytokeratin and epithelial membrane antigen (EMA). Positivity for keratin 19 confirmed that the cultures contained tumour-derived cells, which additionally showed significantly higher activity of the reductive pathway of the steroid-converting enzyme 17p-hydroxysteroid dehydrogenase type 1. That the cultures contained tumour and not normal epithelial cells was further substantiated by the complete absence of the calmodulin-like gene NB-1 in tumour-derived cultures; this is only associated with normal breast epithelia. Eighty-five per cent of cultures established from oestrogen receptor (ER)-positive tumours expressed ER in vitro; this was functional in 66% of cultures, although ER-positive phenotype was gradually lost over time. In conclusion, epithelial cells can be isolated and maintained as short-term cultures from primary breast tumours irrespective of histopathological or clinical details, providing a model system with a greater biological and clinical relevance than breast cancer cell lines.

“…Human breast tumor cell lines, however, are difficult to establish in culture (Smith et al, , 1987. Moreover, breast tumor cells are frequently contaminated with normal epithelial, stromal or mesothelial cells that demonstrate initial in vitro growth, making it difficult to determine the source of the proliferating cultured cells (McCallum and Lowther, 1996). Although about 50-70 human breast cancer lines have been described in publications, the number of breast tumor cell lines that have been adequately characterized and are widely used is only about 20 .…”

“…Almost all of the primary tumor cell lines were derived from patients who also had nodal metastases . Additional problems with the use of currently available breast cancer cell lines include slow growth rates in vitro (McCallum and Lowther, 1996), and lack of hormonal responses. MCF-7 is the most widely studied breast carcinoma cell line because of its steroid receptor status and estrogen sensitivity (Levenson and Jordan, 1997), whereas other cell lines that have low steroid receptor expression (such as PMC42) are not widely used .…”

The repository also includes breast epithelial and stromal cell strains derived from non cancerous breast tissue as well as peripheral blood mononuclear cells. The new breast tumor cell lines have been deposited at the ATCC repository for unrestricted distribution.

Abstract. Breast cancer is a major health burden, responsible for >10% of all cases of cancer worldwide. Advances in breast cancer diagnosis and treatment have contributed to an improved rate of survival, although mortality rates remains significantly high. The establishment of breast cancer cell lines is an important model for understanding biological processes involved in this disease and for identifying potential therapeutic targets. The novel human breast cancer cell lines, MACL-1 and MGSO-3, were used in this study to identify possible surface antigens by antibodies directed against two commercial breast cancer cell lines MCF-7 and MDA-MB-231. We purified a 37 kDa antigen by affinity chromatography from MDA-MB-231, and its N-terminal amino acid sequence was homologous to glyceraldehyde-3-phosphate dehydrogenase (GAPDH). Therefore, immunohistochemical experiments, using specific monoclonal antibodies, evidenced a co-localization of GAPDH and Na + /K + -ATPase on the surface of commercially available and recently established breast cancer cell lines. It is of note that Na + /K + -ATPase was used as a plasma membrane marker. This finding opens new perspectives for breast cancer diagnosis and treatment since GAPDH could be used as a biomarker or as a potential therapeutic target in breast cancer. IntroductionCancer is a public health problem worldwide. Among the various types of cancer, breast cancer is the most common in women, in both high and low-resource settings, and is responsible for over one million of the estimated 10 million neoplasms diagnosed in both sexes worldwide each year (1). It is also the primary cause of death among women globally, responsible for ~375,000 deaths in the year 2000 (1). Although the 5-year survival rate has greatly increased as a result of advances in detection and treatment, many breast cancer patients still die from metastatic disease. Therefore, more effective methods of prevention and treatment are greatly needed.Cell cultures, established directly from patients, are an important model for examining and manipulating the potentially relevant molecules and cellular processes underlying malignant breast disease. However, selective culture of neoplastic cells and successful establishment of new cell lines have rarely been reported from primary breast carcinomas (2,3).The discovery of T-cell recognition and subsequent lysis of human tumors led to the identification of specific oncoproteins or mutated oncogenes (e.g., MUC-1, HER-2, CEA, and p53) (4-7). Many of these tumor antigens are found on normal tissues, but in cases of oncogenesis, are recognized by the immune system due to their overexpression. Some proteins are tumor-specific, but others, such as the universal tumor Ag hTERT, are broadly expressed by most tumor cells (8,9).In the present study, we describe a potential therapeutic target antigen on breast cancer cell lines, established from primary breast carcinoma by Correa et al (9). Using antibodies directed against the commercial cell lines MCF-7 and MDA-MB-231, we we...
