Video abstract for Cell 169(5), 2017

Billions of blood cells die every day and need to be replaced by new ones. In this video, Andreas Trumpp (DKFZ) and group leader Nina Cabezas-Wallscheid show that Vitamin A is a key signal that controls both the transition of hematopoietic stem cells from a "sleep-mode" state called dormancy to an active state and how Vitamin A metabolites may help to improve treatment of blood disorders and leukemias.
