*Research Summary*
Stem cells and cancers are tightly inter-related. Stem cells are oftentimes are the cell of origin for cancers. Also cancers have a subpopulation of cells, so called cancer stem cells (CSCs, a.k.a. tumor-initiating cells), which have stem cell-like characteristics and are considered the source of cancer recurrence. On the other hand, cancer is one of major aging diseases, and stem cells and stem-cell derived organs are the potential sources for anti-aging medicine. Therefore, stem cell research and cancer research are cross-connected and mutually applicable.
