title: Cardiovascular regeneration: pushing and pulling on progenitors.
abstract: In this issue of Cell Stem Cell, Zaruba et al. (2009) describe a pharmacoregenerative strategy for myocardial infarction. Using G-CSF to release progenitors from bone marrow and protease inhibition to prevent degradation of the homing signal, SDF-1, the authors achieve increased recruitment to the heart and improved heart function.
