title: Identifying the perpetrator in medulloblastoma: Dorian Gray versus Benjamin Button.
abstract: Tumors contain a subpopulation of tumor-propagating cells (TPCs) that are critical for their growth. In this issue, Read, Wechsler-Reya, and colleagues show that in an animal model of medulloblastoma, TPCs express the surface marker CD15 and have properties distinct from neural stem cells.
