y, Ruggero De Maria of the Istituto Superiore di Sanita in Rome and colleagues found the same CD133 cells started tumours when injected into immune-deficient mice.

These two studies are the first to show that cancer stem cells are responsible for colon tumours.

That two independent research groups identified colon cancer stem cells reveals the power of this hypothesis, Dirks says.

"The big challenge now is to learn how to target and kill these cells," he says, “As other studies have shown that cancer stem cells in brain tumors are resistant to radiation and leukemic stem cells seem to be resistant to chemotherapy.”

To understand the molecular program of colon cancer stem cells seems to be their next step and also to find out if the cells have properties that make them resistant to chemotherapy. They hope to be funded by the new Ontario Institute of Cancer Research.

"Colon cancer is one of the most common forms of human cancer, but we don't know a lot about the genetics of how it starts," says Dick."It's important to try and understand these (cancer stem) cells."

Colon cancer is the fourth most dangerous cancer , killing 655,000 people every year, according to World Health Organisation.
