title: Metabolic makeover for HSCs.
abstract: Hematopoietic stem cells (HSCs) must at times exit quiescence to divide and produce differentiated blood cells. In this issue of Cell Stem Cell, Takubo et al. (2013) and Yu et al. (2013) show that these opposing actions require distinct metabolic programs to meet the changing energy demands of self-renewing HSCs.
