What are 4T1 cells?
4T1 is a breast cancer cell line derived from the mammary gland tissue of a mouse BALB/c strain. 4T1 cells are epithelial and are resistant to 6-thioguanine. In preclinical research, 4T1 cells have been used to study breast cancer metastasis as they can metastasize to the lung, liver, lymph nodes, brain and bone.
Do breast cancer cells have estrogen receptors?
Hormone status of breast cancers includes: Estrogen receptor (ER) positive. The cells of this type of breast cancer have receptors that allow them to use the hormone estrogen to grow. Treatment with anti-estrogen hormone (endocrine) therapy can block the growth of the cancer cells.
Do all cells have estrogen receptors?
Estrogen receptors (ERs) are a group of proteins found inside cells. They are receptors that are activated by the hormone estrogen (17β-estradiol)….Estrogen receptor.

Are 4T1 cells triple-negative?
4T1 is a triple-negative mouse breast cancer cell line. Pharmatest utilises a 4T1 cell line with stable expression of green fluorescent protein (GFP) enabling easy and efficient detection of whole-body tumour burden. Use of immunocompetent mice in 4T1 models allows efficacy testing of immonomodulatory compounds.
Are 4T1 cells human?
The tumor growth and metastatic spread of 4T1 cells in BALB/c mice very closely mimic human breast cancer. This tumor-derived cell line is an animal model for stage IV human breast cancer.
What type of receptor is the estrogen receptor?
Estrogen receptors (ERs) are members of the superfamily class of nuclear receptors located in either the cell cytoplasm or nucleus and which function as transcription factors (Lovejoy, 2005).
Do all breast cells have estrogen receptors?
Normal breast cells and some breast cancer cells have receptors that attach to the hormones estrogen and progesterone, and need these hormones for the cells to grow. Breast cancer cells may have one, both, or none of these receptors.
What types of cells have estrogen receptors?
Is 4T1 immunogenic?
4T1 is poorly immunogenic and highly metastatic, characteristics shared with advanced human cancers (16). Despite the extensive use of these tumor cell lines in cancer research, little genetic characterization is available for either of them.
