Colorectal cancer ‐initiating cells caught in the act

Our increased awareness of the clonal organization of many hematological and solid cancers has dramatically changed our view on the design of novel therapeutic approaches for cancer. Tumor‐initiating cells (TIC) (a.k.a. cancer stem cells) are on the apex in this hierarchy and can self‐renew and differentiate, thereby continuously fueling tumor growth and metastasis formation. This process was previously thought to be unidirectional. Self‐renewing TIC therefore represent highly attractive targets for therapeutic intervention. A poignant commentary on three recent papers using genetic fate mapping to demonstrate that LGR5+ cells are essential for colorectal cancer tumor growth and metastasis.
