Biological Pathways And Processes Underlying The Cardiac Regenerative Response Post-Injury In Small And Large Mammals, Eric Yang Zhang

All ETDs from UAB

Mammalian cardiomyocytes exit the cell-cycle shortly after birth. Consequently, the adult heart is unable to properly compensate for cardiac muscle lost to injury. As such, heart failure has remained the leading cause of death in the developed world for more than three decades. In this work, we illustrate our findings in using novel in-vivo animal models to examine two regenerative phenomena observed following myocardial injury:i.) neonate cardiomyocyte proliferation in large mammals ii.) the ‘paracrine effect’ as mediated by mesenchymal stromal cells In i.) we use a large animal model of myocardial injury during the early postnatal develop-mental stage to establish …
