Research Project
The structure and function of the human heart is irrevocably changed after heart attack, resulting in considerable mortality and morbidity. Until recently, the contractile cells of the heart were thought to be largely quiescent and non-proliferative after infarction. However, recent evidence published by my supervisor Dr Enzo Porrello, suggests that neonatal mice are capable of regenerating after heart attack through a process that relies on the proliferation of heart contractile cells and the replacement of cardiac scarring with the healthy myocardium (Porrello et al., Science, 2011; Porrello et al., PNAS, 2013).
In 2006, Shinya Yamanaka discovered that the expression of 4 factors in terminally differentiated somatic cells “reprogrammed’ their cellular identity into pluripotent stem cells (cells able to differentiate into any cell type in the body). By utilizing the paradigm of cellular reprogramming, my project aims to utilize neonatal cardioregenerative genes to reprogram non-proliferative adult hearts and pluripotent stem cell-derived mature human cardiac organoids into a neonatal-like proliferative state to facilitate heart regeneration. This project is at the cutting-edge of the regenerative and cardioregenerative biological fields, has the potential to make a substantial contribution to what we know about cardiac regeneration and produce promising candidates for stimulating human cardiac regeneration after heart attack.
