Our group aims at understanding the molecular basis of inherited cardiac diseases, such as arrhythmias and primary cardiomyopathies, by using cardiac cells differentiated from human induced pluripotent stem cells and CRISPR/Cas9 gene-editing technology, with the final goal of boosting the development of newly effective therapies.

The challenge

Cardiovascular diseases represent a major cause of morbidity and mortality worldwide. Despite progresses in the field, preclinical studies on humans are limited, due to the difficult accessibility to human heart tissue, the challenges to isolate and grow human cardiac cells ex-vivo and their limited proliferative capacity; thus, knowledge accumulated so far is mainly based on animal-based models, which however carry some limitations due to species-specific differences in heart pathophysiology compared to humans. Fortunately, the discovery of induced pluripotent stem cells (iPSCs) in 2006, hasmarked the beginning of a new era for the cardiovascular biology studies, as for all field of biomedical research. These cells provide an autologous source of human cells and bear the same characteristics of embryonic stem cells (ESCs), i.e. the ability to proliferate indefinitely and to differentiate into all cell types of the human body. We already know how to differentiate iPSCs into functional cardiomyocytes (CMs) and other cardiovascular-relevant cells, but as in other medical specialties, to unleash the full applicative potential of iPSCs as platform for disease modeling, pharmacogenomics and drug screening, we need first to understand and better direct the differentiation and maturation process, thanks to new bioengineering technologies and the development of cell-based 3D structures and organoids.

Main research areas

iPSC-powered models of cardiac disease mechanisms

One of our main line of research is the development of human in vitro cardiac models, using cellular reprogramming and specific cardiac differentiation protocols, to serve as platforms for the identification of new disease mechanisms and for testing potential new therapeutic approaches and diagnostic/prognostic markers. Within the last ten years we have already generated patient-specific models together with CRISPR/Cas9 gene-edited isogenic pairs of several genetic cardiomyopathies and/or arrhythmias (e.g. DCM-dilated cardiomyopathy, CPVT-catecholaminergic polymorphic ventricular tachycardia) and deeply investigated their functional and molecular properties.

Development of new strategies toward maturation of iPSC-based models

This line of research is mainly devoted to the development of strategies and differentiation protocols to improve maturation of cells generated from iPSCs. Indeed, despite they can be virtually converted into any cell type, iPSC-CMs are often immature, showing morpho-functional, molecular and metabolic properties more similar to fetal than adult cardiomyocytes. This represents a major hurdle for the full applications of iPSC, especially in the context of late-onset disorders and for cardiac regeneration purposes. We are exploring different approaches, such as the implementation of self-assembly cellular protocols to form 3D cardiac microtissue and cardiac organoids, the use of organ-on-chip platforms, in collaboration with Politecnico di Milano and its spinoff BiomimiX, and the use of a new technology based on optical excitation of light-sensitive organic semiconductor polymers, in collaboration with a group of the Italian Institute of Technology and within the H2020-FETOPEN LIONHEARTED project.
