Cell‐free DNA is released from tumor cells upon cell death: A study of tissue cultures of tumor cell lines
1 Jan 2003
Abstract excerpt
To determine the source of cell-free DNA detected in the serum of cancer patients, we monitored the release of cell-free DNA and tumor markers from tumor cell lines using the cell culture technique. During the first 6 days of cell culture, we found very low concentrations of DNA and a steady increase of the CA 125 released from the SK-BR3 tumor cell lines during cell growth. A sudden increase of cell-free DNA...
