MCF7

Human

MCF-7 is a breast cancer cell line isolated in 1970 from a 69-year-old White woman. MCF-7 is the acronym of Michigan Cancer Foundation-7, referring to the institute in Detroit where the cell line was established in 1973 by Herbert Soule and co-workers. MCF7 are epithelial cells isolated from the breast tissue of a 69-year-old, White, female patient with metastatic adenocarcinoma. Use these cells in your breast cancer research.

Detection of Apoptosis Assays

Apoptosis (programmed cell death) plays a vital role in embryonic development, homeostasis, functioning of immune system and wound repair. The ability to evade induction of apoptosis has been used by cancer cells to survive against host defense mechanisms. The molecular mechanisms involved in cancer cell apoptosis have been well documented and it involves certain biochemical events such as DNA fragmentation, chromatin condensation, cell organelle degradation and protein cleavage, etc. The extrinsic and intrinsic (mitochondrial) pathways are the two major pathways involved in apoptosis. With the available techniques and assays, a number of apoptosis inducing agents (natural compounds, synthetic compounds, nano-formulations, peptides and enzymes) in many cancer cells have been identified. Selection of an assay for apoptosis detection is based on factors such as apoptotic pathway, nature of drug, cell type being used and the method of analysis.
