In the context of cancer, like normal tissues, various cancerous tissues also harbor a minor population of cells with enormous self-renewal and tumor-initiating capacity. Such cells are referred to as tumor-initiating cells or cancer stem cells, which offer an attractive target for cancer therapy  provided that normal stem cells are spared from the side effects of therapy. A number of molecular events that mark stem cell aging also occur in tumors in the elderly  and, as such, play important roles in the processes of cancer and aging, suggesting that these two processes are intertwined.Comment: The full text of this article is available via PubMed Central (PMC).
