CAFs 1737 cells are cancer-associated fibroblasts derived from a tumor microenvironment. These cells are commonly used in research to study the role of fibroblasts in tumor growth, metastasis, and drug resistance. They can influence tumor cell behavior through cell-cell interactions and the secretion of growth factors and extracellular matrix components., These cells are typically cultured in a standard fibroblast culture medium supplemented with serum and antibiotics.
