Summary:
Stem cells -- the master cells that give rise to all the blood and tissue in the body -- may also be responsible for tumors, according to two separate studies. Canadian and Italian researchers both found that specialized colon cancer stem cells appeared to be the sources of colon cancer tumors in mice. Their findings, published in the journal Nature, support the belief that future cancer treatments will have to home in on cancer stem cells.
