The Hs 578T cell line is a human breast cancer cell line derived from a carcinoma of the mammary gland. These cells exhibit an epithelial-like morphology and are characterized by their adherent growth pattern. The Hs 578T cell line is commonly used in cancer research, particularly for studying the mechanisms of breast cancer progression and metastasis. The cells display mutations in the TP53 gene, which is a critical tumor suppressor gene, and this mutation is often associated with the aggressive behavior of certain cancer types.
Hs 578T cells are hormone receptor-negative, meaning they do not express estrogen or progesterone receptors, which classifies them as triple-negative breast cancer cells. This makes them particularly valuable in research focused on treatments for this aggressive subtype of breast cancer, which typically has fewer therapeutic options and a poorer prognosis compared to hormone receptor-positive breast cancers. Researchers utilize the Hs 578T cell line to explore various aspects of tumor biology, including cell proliferation, migration, and response to chemotherapy and targeted therapies.
The Hs 578T cell line also expresses vimentin, a marker associated with epithelial-to-mesenchymal transition (EMT), a process that plays a crucial role in cancer metastasis. Studies involving these cells help to elucidate the molecular pathways involved in EMT and provide insights into potential therapeutic targets to inhibit cancer spread. Additionally, the Hs 578T cells have been used in drug screening assays to identify compounds with potential anti-cancer activity.
—
- Receptors expressed: Receptor expression: estrogen receptor, not expressed
- Tumorigenic: No
- cultureMedium: DMEM, w: 4.5 g/L Glucose, w: 4 mM L-Glutamine, w: 3.7 g/L NaHCO3, w: 1.0 mM Sodium pyruvate (Cytion article number 820300a)
- supplements: Supplement the medium with 10% FBS
- dissociationReagent: Accutase
- 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.
- fluidRenewal: 2 to 3 times per week
- freezeMedium: As a cryopreservation medium, use complete growth medium (including FBS) + 10% DMSO for adequate post-thaw viability, or CM-1 (Cytion catalog number 800100), which includes optimized osmoprotectants and metabolic stabilizers to enhance recovery and reduce cryo-induced stress.
