MCF-7

MCF-7 is a breast cancer cell line isolated in 1970 from a 69-year-old Caucasian woman. MCF-7 is the acronym of Michigan Cancer Foundation-7, referring to the institute in Detroit where the cell line was established in 1973 by Herbert Soule and co-workers. The Michigan Cancer Foundation is now known as the Barbara Ann Karmanos Cancer Institute.

Prior to MCF-7, it was not possible for cancer researchers to obtain a mammary cell line that was capable of living longer than a few months.

The patient, whose name, Frances Mallon, is unknown to the vast majority of cancer researchers, died in 1970. Her cells were the source of much of current knowledge about breast cancer. At the time of sampling, she was a nun in the convent of Immaculate Heart of Mary in Monroe, Michigan under the name of Sister Catherine Frances.

MCF-7 and two other breast cancer cell lines, named T-47D and MDA-MB-231, account for more than two-thirds of all abstracts reporting studies on mentioned breast cancer cell lines, as concluded from a Medline-based survey.
