Cancer Stem Cell

Cancer stem cells (CSCs) are cancer cells (found within tumors or cancers) that possess characteristics associated with normal stem cells. They are defined by their ability to (i) fully recapitulate the tumor of origin when transplanted, and (ii) self-renew. Both properties suggest that CSCs are required for tumor maintenance and metastasis; thus, it has been predicted that CSC elimination is required for cure. If treatments of cancer do not properly destroy enough CSCs, the tumor will reappear.
