Abstract
The majority of breast cancer research is conducted using established breast cancer
cell lines as
in vitro models. An alternative is to use cultures established from primary breast tumours.
Here, we discuss the pros and cons of using both of these models in translational
breast cancer research.
Nineteen human breast carcinoma cell lines have been established as continuous cultures during the past 6 years in our laboratory. This preliminary report is designed to list the lines by their designated code numbers (MDA-MB) and present a brief summary of their morphological, cytogenetic and biochemical characteristics. Sixteen of our lines were obtained from pleural effusions, two from brain metastases, and one from pericardial fluid. All lines have been shown to be distinct entities and are uncontaminated by HeLa cells or each other. A lq marker chromosome is present in all but one of the lines examined.
