NMuMG cells are a normal murine mammary gland epithelial cell line widely used as a model for studying epithelial-mesenchymal transition (EMT) and mammary gland development. These cells are known for their ability to undergo EMT in response to TGF-beta and are valuable for investigating the molecular mechanisms underlying this process., These cells are provided as a fraction of a TC-100 dish. They are typically cultured in DMEM supplemented with 10% fetal bovine serum and insulin. They are commonly used in studies of cell signaling, cell-cell interactions, and cancer biology.
