summary
CTVT Cancer Line The CTVT cancer line is a murine (mouse) cell line derived from a spontaneous mammary adenocarcinoma in a C57BL/6J mouse. It is widely used in cancer research, particularly for studying metastasis, angiogenesis (blood vessel formation), and the tumor microenvironment. The line’s propensity to metastasize to the lungs and other organs makes it a valuable model for investigating the mechanisms of cancer spread and for testing potential anti-metastatic therapies.[1] Its ease of culture and relatively well-characterized genetic background further contribute to its popularity in the research community.[2] The CTVT line’s significance stems from its ability to recapitulate key features of human cancer metastasis. Unlike many other cancer cell lines, CTVT cells exhibit robust in vivo metastatic behavior, forming secondary tumors in multiple organs following intravenous injection into mice.[3] This characteristic has made it a favored model for studying the role of various factors, including chemokines, growth factors, and extracellular matrix components, in the metastatic cascade.[4] Researchers have also utilized the CTVT line to investigate the efficacy of novel therapeutic approaches targeting metastasis, such as anti-angiogenic drugs and inhibitors of specific signaling pathways.[5] While widely used, the CTVT line has also been the subject of some debate regarding its reproducibility and the interpretation of experimental results. Variations in experimental protocols and mouse strains used in conjunction with the CTVT line have occasionally led to inconsistencies across different studies.[6] Furthermore, the spontaneous nature of the original tumor means the CTVT line possesses a complex genetic background, which can complicate the identification of specific genetic drivers of metastasis.[7] The CTVT cancer line remains a crucial tool for cancer researchers seeking to understand and combat metastasis. Its continued use allows for the investigation of fundamental biological processes and the development of new therapeutic strategies, despite ongoing efforts to address concerns about reproducibility and genetic complexity.[8]
