Main Research Themes:
• Human pluripotent stem cell-derived cardiomyocytes (hPSC-CMs) as cardiac disease models
• hPSC-CMs platforms for drug screening and safety pharmacology
• Three-dimensional (3D) cardiac microtissues
We use human pluripotent stem cells to model and study the genetic causes of cardiovascular diseases, in particular channelopathies. Long-QT syndrome (LQTS) is an arrhythmogenic disorder characterised by prolongation of the QT interval on the surface electrocardiogram, which can lead to sudden cardiac death. We have demonstrated that patient-specific hPSC-CMs are able to recapitulate the autosomal dominant forms of LQTS type 1 and type 2 and the rare recessive form Jervell and Lange-Nielsen syndrome.
Genome-engineering tools enable us to directly test the cellular consequences of precise genetic changes. We are applying efficient methods to edit hPSCs to generate isogenic lines. Investigating the electrophysiolgical phenotype of isogenic hPSC-CMs is helping us to explain the molecular and cellular basis of inherited cardiac arrhythmia. By leveraging these specific and isogenic disease lines we are also developing platforms to screen and identify cardio-active molecules that could revert pathological phenotypes.
The heart is a complex tissue composed by several cell types including cardiomyocytes, endothelial cells, smooth muscle cells, fibroblasts and other connective tissue cells. We are using hPSCs to develop 3D-cardiac microtissue constructs comprising both cardiomyocytes and non-myocyte cells to more accurately reproduce the multicellular organization and the dynamic function of native heart. These constructs will assist cardiovascular disease modelling and drug screening.
