title: Description of a new human breast cancer cell line, IIB-BR-G, established from a primary undifferentiated tumor.
abstract: The establishment of a new human breast cancer cell line (IIB-BR-G) was successful after a previous growth of the cells isolated from a breast primary tumor in a female nude mouse. The IIB-BR-G cell line and the primary tumor do not express estrogen or progesterone receptors. Vimentin and keratin expression were found in the cell line and in the nude mouse tumor. This cell line displays high morphological heterogeneity with atypical multinucleated megacells, and it is capable of anchorage-independent growth and tumor formation in nude mice. The cytogenetic analysis confirmed its human origin and revealed multiple marker chromosomes and extensive chromosomal alterations including rearrangements, gains, losses, isochromosomes, and double minutes (DMs).
