The TRAIN-HEART consortium, funded by the European Commission (2019-2023), is made up to train a league of 15 promising fellows that harness novel insights in the pathogenesis of ischemic heart failure, study the therapeutic potential of existing RNA therapeutics and improve its efficacy by the design of novel drug delivery systems.


TRAIN-HEART brings together leading academic teams and (biotech) companies covering various disciplines ranging from fundamental research to clinical pharmacology and gene therapy to drug delivery applications, have teamed up in the European Union.

Research Programme

The TRAIN-HEART network aims to gain viable insight in the pathogenesis of ischemic heart failure which will serve as a basis for drug discovery and drug delivery efforts that aim to therapeutically target specific molecules and mechanisms within cardiomyocytes for the treatment of ischemic heart failure.

How to repair a broken heart with pluripotent stem cell-derived cardiomyocytes?

Heart regeneration addresses a central problem in cardiology, the irreversibility of the loss of myocardium that eventually leads to heart failure. True restoration of heart function can only be achieved by remuscularization, i.e. replacement of lost myocardium by new, force-developing heart muscle. With the availability of principally unlimited human cardiomyocytes from pluripotent stem cells, one option to remuscularize the injured heart is to produce large numbers of cardiomyocytes plus/minus other cardiovascular cell types or progenitors ex vivo and apply them to the heart, either by injection or application as a patch. Exciting progress over the past decade has led to the first clinical applications, but important questions remain. Academic and increasingly corporate activity is ongoing to answer them and optimize the approach to finally develop a true regenerative therapy of heart failure.
