Colo-205 Cells

The COLO-205 cell line is a human colorectal adenocarcinoma cell line first established from the metastatic site of the ascites in a 70-year-old Caucasian male. Characterized by its epithelial cell morphology, this cell line is frequently utilized in biomedical research focused on colorectal cancer, particularly in studies related to cancer biology, drug response, and metastatic mechanisms. COLO-205 cells exhibit a hyperdiploid karyotype and are known to form moderately well-differentiated adenocarcinomas when xenografted into immunodeficient mice. COLO-205 cells express several key oncogenic and tumor suppressor pathways, making them a valuable model for pharmacological testing and cancer research. They are responsive to tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) making them suitable for apoptosis studies. Furthermore, these cells have been used extensively to investigate the pharmacodynamics of various chemotherapeutic agents, providing insights into the mechanisms of action and resistance in colorectal cancer therapy. Research utilizing the COLO-205 line has contributed significantly to understanding the biological behaviors typical of colorectal adenocarcinomas, including cellular proliferation, differentiation, and interaction with anticancer drugs.
