Stem cell population may hold colon cancer clues

Vanderbilt-Ingram Cancer Center researchers have identified a new population of intestinal stem cells that may hold clues to the origin of colorectal cancer.

This new stem cell population, reported March 30 in the journal Cell, appears to be relatively quiescent (inactive) – in contrast to the recent discovery of intestinal stem cells that multiply rapidly — and is marked by a protein, Lrig1, that may act as a “brake” on cell growth and proliferation.

The researchers have also developed a new and clinically relevant mouse model of colorectal cancer that investigators can now use to better understand where and how the
