Stem cells on the move

Mobilization of hematopoietic stem cells (HSCs) from the bone marrow is the standard method to collect grafts for stem cell transplants, but sometimes insufficient HSCs are mobilized. A new study suggests that epidermal growth factor receptor (EGFR) inhibition can augment mobilization, bringing us one step closer to an universal method to obtain HSCs for transplantation (pages 1141–1146).
