Cultured cell lines from human breast cancer biopsies and xenografts.

Abstract:

:Eighty-five breast cancer specimens were processed as part of a program in tumor acquisition, propagation, and preservation for biotherapy. Nine long-term culture cell lines were developed. Four cell lines were from solid tumor metastases, two lines were from pleural fluid specimens, and three were from xenograft tumors grown in nude mice. Two of the xenograft-derived cell lines were from biopsies which produced tumor cell lines as well. Success in establishing cultures did not correlate with the viability of the biopsy received. Poor tumor cell attachment to culture plastic was the most common problem. For certain specimens, attachment and growth were enhanced on collagen and extracellular matrix substrates. Collagen was beneficial in the development of one cell line. The cell lines were characterized and each of the lines contained more nuclear DNA than found in normal cells. Four of five lines tested were tumorigenic in nude mice. Five of nine were clonogenic in soft agar. Each of the cell lines tested reacted with at least two anti-tumor monoclonal antibodies. Xenograft and biopsy-derived cell lines from the same tumor were similar in their characteristics. While breast cancers are indeed difficult to establish and propagate in culture, the use of xenografts and special substrates appears to be beneficial in the development of cell lines from some tumors.
