TD is a human breast cancer cell line commonly used in biomedical research involving the hormonal expression of cancer cells. Breast cancer is cancer that develops from breast tissue. Signs of breast cancer may include a lump in the breast, a change in breast shape, dimpling of the skin, fluid coming from the nipple, a newly inverted nipple, or a red or scaly patch of skin. In those with distant spread of the disease, there may be bone pain, swollen lymph nodes, shortness of breath, or yellow skin.

T47D Cell Line human | Sigma-Aldrich

Human breast cancer cell line commonly used in biomedical research involving the hormonal expression of cancer cells. Human lung cancer cell line commonly used in cancer research and drug development. Calu-3 cells are epithelial and can act as respiratory models in preclinical applications. Human primary glioblastoma cell line that is commonly used in brain cancer research. Epithelial morphology and was obtained from a male patient of uncertain age in at Uppsala University. Cell line that was isolated from a year-old female human in , and is commonly used in breast cancer research. MDA-MB 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.

Choosing the right cell line for breast cancer research

When TD human breast cancer cells were grown in medium supplemented with foetal calf serum FCS which had been depleted of endogenous oestradiol E2 by dextran-charcoal treatment CS-FCS tamoxifen and E2 had biphasic effects on cellular proliferation. At higher doses tamoxifen These observations may explain features of the clinical phenomenon of tamoxifen-induced tumour flare: tamoxifen may temporarily exert a weak oestrogen agonist activity on the tumour as its concentration gradually increases after initiation of treatment; further, patients with tamoxifen-induced tumour flare often experience a remission with continued administration of the drug, presumably as the intratumour concentration of tamoxifen continues to accumulate to an inhibitory level.

Use of the human TD cell line derived xenograft CDX is vital for studying novel cancer therapeutics. Breast cancer, the 2 nd leading cause of death for American women, is extremely heterogeneous. Thus, any therapeutic studies performed in vitro must be followed by a well-designed xenograft study. The combination of an immunocompromised mouse with TD human cancer cells enables researchers to study anti-tumor efficacy of lead compounds e. Development of an anti-cancer therapeutic requires intense, well planned studies that follow a streamlined path for success.
