Abstract

Blood cells by heartbeat Following initiation of the heartbeat in vertebrate embryos, cells lining the aorta, the placental vessels and the umbilical and vitelline arteries begin to form haematopoietic cells. It has been suggested that biomechanical forces imposed on the vascular wall by the heartbeat, which sets up vascular flow and wall shear stress, could be the cue for the production of these early blood cells. Working with mouse embryonic stem cells differentiated in vitro and in mouse embryos, Adamo et al. show that exposure to fluid shear stress increases haematopoietic colony-forming potential and expression of haematopoietic markers both in vitro and in vivo. The confirmation of a link between the initiation of vascular flow and embryonic blood cell development provides new pointers for research on the production of haematopoietic progenitors for possible use in stem-cell-based therapies.
