USC Researchers recently made significant strides toward settling a decades-old debate centering on the role played by stem cells in cancer development. According to the study's findings, genes that are reversibly repressed in embryonic stem cells are over-represented among genes that are permanently silenced in cancers; this link lends support to the increasingly discussed theory that cancer is rooted in small populations of stem cells.
