Scientists study the behaviour of isolated cells grown in the laboratory for insights into how cells function in the body in health and disease. Experiments using cell culture are used for developing new diagnostic tests and new treatments for diseases. This is a list of major breast cancer cell lines that are primarily used in breast cancer ...
MDA-MB-468 is a cell line that was isolated from a 51-year-old female human in 1977, and is commonly used in breast cancer research. MDA-MB-468 cells were extracted from a pleural effusion of mammary gland and breast tissues, and have proven useful for the study of metastasis, migration, and breast cancer proliferation.
MCF-7 is a breast cancer cell line isolated in 1970 from a 69-year-old White woman. [1] 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. [2] The Michigan Cancer Foundation is now known as the Barbara Ann Karmanos Cancer ...

Staging breast cancer is the initial step to help physicians determine the most appropriate course of treatment. As of 2016, guidelines incorporated biologic factors, such as tumor grade, cellular proliferation rate, estrogen and progesterone receptor expression, human epidermal growth factor 2 (HER2) expression, and gene expression profiling into the staging system.
Metastatic breast cancer cells frequently differ from the preceding primary breast cancer in properties such as receptor status. The cells have often developed resistance to several lines of previous treatment and have acquired special properties that permit them to metastasize to distant sites.
Cancer cell heterogeneity can cause disease progression when molecularly targeted therapy, fails to kill those tumor cells which do not express the marker, then divide and mutate further, creating a new heterogeneous tumour. In breast cancer models of the mouse the immune microenvironment affects susceptibility to neoadjuvant chemotherapy. In ...
The cancer stem cell hypothesis proposes that the different kinds of cells in a heterogeneous tumor arise from a single cell, termed Cancer Stem Cell. Cancer stem cells may arise from transformation of adult stem cells or differentiated cells within a body. These cells persist as a subcomponent of the tumor and retain key stem cell properties.
