Genetically engineered 'queen' cancer cells.

Geneticists at the Massachusetts Institute of Technology have developed a new cell culturing medium that does something amazing: It allows human cells to transform into so-called 'queen' cancer cells, cancer cells that reproduce rapidly and produce mutants that become the actual tumours. Think of them as stem cells that specialize in producing cancers as we normally think of them. Not all malignant cells are capable of doing this, most just sit there and use up resources and oxygen and reproduce, but don't actually break off and spread to other parts of the body. This germ line of cells came about …
