SK-CO-1: Human Colorectal Adenocarcinoma Cell Line


SK-CO-1: Human Colorectal Adenocarcinoma Cell Line



SK-CO-1 is a human colorectal adenocarcinoma cell line that displays epithelial morphology and grows in adherent tissue culture. In culture, these cells are capable of invading through an extracellular matrix, such as Matrigel. SK-CO-1 cells do not form tumors when injected into immunocompromised mice, and rarely form colonies in soft agar. These cells have oncogenic mutations in K-Ras (G12V) and adenomatous polyposis coli (APC) proteins.


This cell line was established in 1972 from a metastatic site (ascites) in a 65-year-old Caucasian male with colorectal adenocarcinoma.
