Dr Johannes Bargehr

Research Interests

Dr Johannes Bargehr is a Cardiology Academic Clinical Fellow with a specialty interest in regenerative cardiovascular medicine. Johannes completed an MPhil in Translational Medicine and Therapeutics at Cambridge and subsequently a PhD with Dr Sanjay Sinha at the Wellcome-MRC Cambridge Stem Cell Institute. His Cambridge doctoral thesis examined the role of human embryonic stem cell (hESC)-derived epicardial cells in myocardial graft development. During this time he also spent over a year in Prof. Charles Murry’s lab at University of Washington in Seattle to test the functionality of hESC-derived epicardium as a regenerative therapeutic following myocardial infarction. 

Aiming to remuscularise lost myocardial tissue with the use of hESC-derived cardiomyocytes is a promising approach to effectively treat the underlying problem of ischaemic heart disease. However, associated shortcomings include low cell engraftment, poor proliferation as well as suboptimal vascularisation of cardiac grafts. Johannes has shown that the embryonic function of the epicardial tissue can be exploited to overcome these limitations resulting in markedly enhanced structural and functional properties of hESC-derived cardiomyocytes in vitro and in vivo.      

His future endeavours lie in further optimisation of human stem cell -based heart repair and the translation of his science to a clinical therapy for patients with ischaemic heart disease.
