Engraftment Patterns of Human Adult Mesenchymal Stem Cells Expose Electrotonic and Paracrine Proarrhythmic Mechanisms in Myocardial Cell Cultures

19 Feb 2013

Abstract excerpt

BACKGROUND: After intramyocardial injection, mesenchymal stem cells (MSCs) may engraft and influence host myocardium. However, engraftment rate and pattern of distribution are difficult to control in vivo, hampering assessment of potential adverse effects. In this study, the role of the engraftment patterns of MSCs on arrhythmicity in controllable in vitro models is investigated. METHODS AND RESULTS: Cocultures...
