Alan P. Fields, Ph.D., and Dr. Monica Flynn Jacoby, professor of cancer studies at Mayo Clinic's campus in Florida, talk about the publication of his team's latest discovery. A team of cancer biologists at Mayo Clinic's campus in Florida is reporting in the February, 10, 2014, issue of Cancer Cell the discovery of two oncogenes that work together to sustain a population of cells in lung squamous cell carcinoma, which may be responsible for the lethality of the disease. When these cells, termed cancer stem cells, are inhibited, tumors cannot develop.
