3T3 cells

3T3 cells are a type of cells derived from mouse embryonic tissue, commonly used in scientific research. They are fibroblasts, which are cells that form connective tissue and provide structural support in the body. In laboratories, 3T3 cells are valuable for studying cell growth, cancer, and infection, as they can multiply easily and behave in predictable ways. Their name comes from the original method of cultivation: "3T" for "Transfer, Transfer, Transfer," and "3" indicating the initial cell number. These cells are a standard model for understanding basic cellular processes in mammals.
