Cardiovascular diseases (CVDs) are the leading cause of mortality in developed countries worldwide. Many cardiac disorders caused by genetic and/or environmental factors are characterized by cell death, inflammation, fibrosis and tissue remodeling leading to structural, electrical, and metabolic alterations.

The availability of appropriate and reliable in vitro models able to resemble the human heart is pivotal in cardiovascular research in order to increase our understanding of molecular mechanisms underlying cardiac (patho)physiology for the development of novel therapeutic approaches.

Therefore, the discovery of induced pluripotent stem cells (hiPSCs) and their differentiation potential into cardiovascular cell types brought new prospects for the development of advanced tools for disease modeling, drug discovery and personalized/regenerative medicine. Importantly, human iPSC-derived cardiac cells, carrying the genetic background of donor somatic cells, allow to investigate genotype-phenotype relationships in monogenic, complex and polygenic or genetically unknown conditions.

Although significant progress has been made, the development of novel approaches to mimic the cellular composition and complex architecture of human cardiac tissue remains an urgent need for generating physiologically relevant tissues for disease modelling, drug screening, and therapeutic repair.

The goal of this Research Topic is to collect state-of-the-art in vitro human cardiac systems enable to improve our understanding of cardiac physiology and diseases, providing more efficient tools for therapy development and personalized medicine. This collection will also provide insights into the future directions to develop more accurate models that best recapitulate the (patho)physiology of the human native tissue.

In this Research Topic, we encourage researchers to contribute with original research articles as well as reviews, methods, commentaries and perspectives from all the areas of stem cell-based cardiac biology, including but not limited to:

• Human stem cell derived cardiac in vitro models
• Pluripotent cell derived spheroids, organoids and engineered heart tissues
• Cardiac tissue engineering approach and organ-on-chip
• Cardiac cell-specific models (atrial, nodal, ventricular)
• Three-dimensional cardiac models for studying cardiac development/physiology
• Patient-specific cardiac model for disease modelling, personalized medicine and clinical application
• Complex in vitro human cardiac models for drug testing and cardiotoxicity
• Maturation of stem cell-derived cardiac cells
• Genome editing for establishing cardiac-specific reporter lines or correcting genetic mutations
• Optimization of differentiation and cell culture practices to achieve high reproducibility in hiPSC disease modeling
