Cancer Stem Cells and Signaling Pathways explores the mechanism of cancer stem cell signaling pathways in cancer advancement, serving as an ideal reference guide for investigators with valuable answers to problems associated with anti-cancer treatments and an understanding of the crosstalk among the signaling pathways in CSC regulation. Despite recent advances in tumor therapy and a greater understanding of their biology, tumors continue to be a prevalent and fatal worldwide. According to a novel paradigm in tumor biology, a small percentage of the cells within a tumor known as cancer stem cells (CSCs) are predicted as a crucial population for tumor progression.
