Acute myocardial infarction activates progenitor cells and increases Wnt signalling in the bone marrow

Abstract

Acute myocardial infarction is associated with an increased metabolic activity and increased levels of progenitor cells within days after AMI. These findings document an activation of the stem cell niche within the BM following AMI, which may have important implications for the optimal timing of cell aspirations used for therapeutic application in patients with AMI.
