Breast cancer cell lines
Description
BT-474 is a human breast cancer cell line, derived from the ductal carcinoma of a 60-year-old female. This cell line is estrogen and progesterone receptor positive, making it a valuable model for studying hormone-responsive breast cancers. BT-474 cells are also characterized by the overexpression of HER2/neu (human epidermal growth factor receptor 2), a protein that is amplified and plays a critical role in the pathogenesis and progression of certain aggressive types of breast cancer.

The BT-474 cell line is extensively used in oncological research to study the molecular mechanisms of breast cancer proliferation and to test therapeutic strategies targeting hormone receptors and the HER2 pathway. These cells are particularly useful for examining the efficacy of HER2-targeted therapies, such as trastuzumab (Herceptin), and for exploring mechanisms of resistance to these treatments. The cell line has also contributed to advancements in understanding how hormonal manipulations affect cancer cell growth and survival, providing insights into potential treatment approaches for hormone-dependent tumors.
Tissue
Breast, mammary gland
Growth properties
The cells grow in compact, slowly growing multi-layered colonies which rarely become confluent. A confluent monolayer is not formed.
Disease
Invasive ductal carcinoma
Age
60 years
Gender
Female
Ethnicity
Caucasian
Morphology
Epithelial-like
Biosafety Level
1
Culture Medium
DMEM:Ham's F12, w: 3.1 g/L Glucose, w: 1.6 mM L-Glutamine, w: 15 mM HEPES, w: 1.0 mM Sodium pyruvate, w: 1.2 g/L NaHCO3 (Cytion article number 820400a)
Medium Supplements
Supplement the medium with 10% FBS, 5 microgram/mL Insulin
Subculturing
Remove the old medium from the adherent cells and wash them with PBS that lacks calcium and magnesium. For T25 flasks, use 3-5 ml of PBS, and for T75 flasks, use 5-10 ml. Then, cover the cells completely with Accutase, using 1-2 ml for T25 flasks and 2.5 ml for T75 flasks. Let the cells incubate at room temperature for 8-10 minutes to detach them. After incubation, gently mix the cells with 10 ml of medium to resuspend them, then centrifuge at 300xg for 3 minutes. Discard the supernatant, resuspend the cells in fresh medium, and transfer them into new flasks that already contain fresh medium.
Fluid Renewal
2 to 3 times per week
Freezing Recovery
Almost 100% recovered cells at |BiggerAs|90% viability
Freeze Medium
Handling of Cryopreserved Cultures

Confirm that the vial remains deeply frozen upon delivery, as cells are shipped on dry ice to maintain optimal temperatures during transit.

Upon receipt, either store the cryovial immediately at temperatures below -150° C to ensure the preservation of cellular integrity, or proceed to step 3 if immediate culturing is required.

For immediate culturing, swiftly thaw the vial by immersing it in a 37° C water bath with clean water and an antimicrobial agent, agitating gently for 40-60 seconds until a small ice clump remains.

Perform all subsequent steps under sterile conditions in a flow hood, disinfecting the cryovial with 70% ethanol before opening.

Carefully open the disinfected vial and transfer the cell suspension into a 15 ml centrifuge tube containing 8 ml of room-temperature culture medium, mixing gently.

Centrifuge the mixture at 300 x g for 3 minutes to separate the cells and carefully discard the supernatant containing residual freezing medium.

Gently resuspend the cell pellet in 10 ml of fresh culture medium. For adherent cells, divide the suspension between two T25 culture flasks; for suspension cultures, transfer all the medium into one T25 flask to promote effective cell interaction and growth.

Adhere to established subculture protocols for continued growth and maintenance of the cell line, ensuring reliable experimental outcomes.

Sterility
Mycoplasma contamination is excluded using both PCR-based assays and luminescence-based mycoplasma detection methods.
To ensure there is no bacterial, fungal, or yeast contamination, cell cultures are subjected to daily visual inspections.
Safety Precautions
When planning to store a cryovial in liquid nitrogen for future thawing, it is mandatory to adhere to stringent safety measures. Appropriate protective gloves and clothing are essential, and the use of a face mask or safety goggles is required during the transfer of frozen samples to or from the liquid nitrogen tank. This is to mitigate the risk of injury from potential cryovial explosions upon removal, which can result in the projection of sharp fragments.
