Is MCF10A triple-negative?

Cell Culture. Culture conditions have been described previously [11]; MCF-7, MCF10A, SKBr3, and MDA-MB-231 were purchased from the American Type Culture Collection (ATCC). MDA-MB-231 cells are characterized as triple-negative/basal-B mammary carcinoma and SKBr3 are HER2+ mammary carcinoma.

What is TNBC cell line?

The latter group is referred to as triple-negative breast cancer (TNBC) based on the lack of these three molecular markers. Generally, hormone receptor expressing breast cancers have a more favorable prognosis than either those with HER-2/Neu amplification or those that are triple-negative [5].

What type of breast cancer is MDA-MB-231?

MDA-MB-231 is a highly aggressive, invasive and poorly differentiated triple-negative breast cancer (TNBC) cell line as it lacks oestrogen receptor (ER) and progesterone receptor (PR) expression, as well as HER2 (human epidermal growth factor receptor 2) amplification2,3.

Is MCF-7 triple-negative?

What does HER2 mean?

HER2-positive breast cancer is a breast cancer that tests positive for a protein called human epidermal growth factor receptor 2 (HER2). This protein promotes the growth of cancer cells.

What is mcf10a?

The MCF 10A cell line is a non-tumorigenic epithelial cell line. The cells are positive for epithelial sialomucins, cytokeratins and milk fat globule antigen. They exhibit three dimensional growth in collagen, and form domes in confluent cultures.

What are tumor cell lines?

Listen to pronunciation. (KAN-ser sel line) Cancer cells that keep dividing and growing over time, under certain conditions in a laboratory. Cancer cell lines are used in research to study the biology of cancer and to test cancer treatments.

What are cell lines?

Cell line. (Science: cell culture) a cell line is a permanently established cell culture that will proliferate indefinitely given appropriate fresh medium and space. lines differ from cell strains in that they have escaped the Hayflick limit and become immortalised.

How long does it take MDA MB 231 cells to adhere?

Do not change the media or split cells before they are about 60% confluent (which can take 5-7 days for MDA-MB-231, depending on how many survive thawing), unless there are a lot of dead cells floating.

What does HER2-positive mean?

HER2 is a growth-promoting protein on the outside of all breast cells. Breast cancer cells with higher than normal levels of HER2 are called HER2-positive. These cancers tend to grow and spread faster than other breast cancers, but are much more likely to respond to treatment with drugs that target the HER2 protein.

Is MCF7 triple positive?

MCF7 and MDA-MB-231 cells represent a striking example in that they are both invasive ductal/breast carcinoma cells, yet they have many phenotypic/genotypic differences: MCF7 are hormone dependent (both estrogen and progesterone receptor positive—ER and PR), while MDA-MB-231 are triple negative.

Can HER2-positive be cured?

HER2-positive breast cancer is highly curable because of the availability of these HER2-targeted therapies, so we treat patients fairly aggressively upfront to reduce the risk of them experiencing a stage IV recurrence.
