ECV-304 Cells

The ECV-304 cell line is a spontaneously transformed cell line derived from human umbilical vein endothelial cells (HUVEC). Originally characterized and utilized as a model of endothelial cell biology, further genomic analysis revealed that ECV-304 cells were contaminated and are genetically identical to the T24 bladder carcinoma cell line. This revelation has significant implications for the interpretation of research data, particularly studies conducted under the assumption that ECV-304 was a true endothelial cell model. Despite its endothelial mischaracterization, ECV-304 has been widely used in studies related to tumorigenesis, cytotoxicity, and drug screening, primarily due to its robust growth characteristics and the ease with which it can be cultured. The cells exhibit epithelial morphology and possess the ability to grow in a monolayer, making them a suitable in vitro model for studying various aspects of cancer biology, including cell proliferation, migration, and the cellular response to therapeutic agents. However, caution must be exercised in the interpretation of past studies where ECV-304 was used as a model of endothelial cells. Given the genetic identification with the T24 cell line, researchers should consider ECV-304 as a bladder carcinoma model rather than an endothelial cell line. This understanding is crucial for the design and interpretation of experiments aimed at investigating cellular behaviors that are relevant to cancer research rather than endothelial cell function.
