4T1 Cells

The 4T1 murine mammary carcinoma cell line is a widely used model in cancer research due to its high similarity to human breast cancer. Derived from a BALB/c mouse, the tumor growth and metastatic spread of the 4T1 cell line closely mimic the behavior of late stage breast cancer in humans. The 4T1 cell line serves as an invaluable tool for studying the progression and metastasis of mammary cancer, including bone metastases and breast cancer metastasis. When injected into BALB/c mice, 4T1 cells spontaneously produce highly metastatic tumors that can spread to various organs such as the lung, liver, lymph nodes, and bone, while the primary tumor continues to grow in situ. This 4T1 syngeneic model is particularly useful for studies of bone metastases and the metastatic phenotype. The 4T1 cell's utility extends to techniques like bioluminescence imaging, histological analyses, and the use of molecular markers to track the spread and impact of metastatic disease. This approach allows for the examination of spontaneous metastasis from primary tumors to distant organs, aided by techniques like flow cytometry to analyze tumor cells and their receptor expressions. The imagable 4T1 model has enabled biophotonic imaging to track tumor growth and metastasis in vivo in animal models, facilitating studies on metastatic cells in target organs and tumor foci. The immunocompetent nature of the mouse 4T1 breast tumor cell line allows for investigations into the role of the immune system and immunity in metastasis, as well as immunotherapy of cancer. Moreover, the 4T1 syngeneic tumor model has been instrumental in omics characterization and fusion gene detection. Overall, the 4T1 mammary carcinoma cell line serves as a versatile tool for studying mammary tumor biology, tumor metastasis, and the development of new treatments in both murine and human contexts.
