Newly created cancer stem cells could aid breast cancer research
...st 13, 2007) In some ways, certain tumors resemble bee
colonies, says pathologist Tan Ince. Each cancer cell in the tumor plays a specific role, and just a fraction of the cells serve as queens, possessing the unique ability to maintain themselves in an unspecialized state and seed new tumors. These cell...
