Insights
Modeling non-genetic heart diseases using human pluripotent stem cell-derived cardiomyocytes (hPSC-CMs) is advancing. However, research on these models significantly lags behind genetic heart conditions, despite their prevalence.
Area of Science:
- Cardiovascular Research
- Stem Cell Biology
- Disease Modeling
Background:
- Non-genetic cardiac pathologies arise from extracellular stress, influenced by intracellular factors and genetics.
- Modeling conditions like hypertrophy and ischemia in human pluripotent stem cell-derived cardiomyocytes (hPSC-CMs) has been challenging due to complex phenotypes.
- Recent advancements in hPSC-CMs physiology and culture have enabled the creation of stress-responsive models.
Purpose of the Study:
- To review the literature on hPSC-CM models for non-genetic cardiac conditions.
- To highlight the underrepresentation of these models compared to monogenic disease models.
- To emphasize the need for increased research in this area.
Main Methods:
- Literature review of published articles on hPSC-CMs modeling non-genetic cardiac diseases.
- Analysis of research trends comparing non-genetic versus monogenic cardiac disease models.
- Synthesis of current understanding of hPSC-CMs' in vitro physiology and stress responses.
Main Results:
- Models for non-genetic cardiac conditions using hPSC-CMs are less numerous than those for monogenic diseases.
- This disparity misrepresents the actual incidence of non-genetic heart disease causes in the human population.
- Despite challenges, hPSC-CMs are increasingly capable of recapitulating in vivo pathological phenotypes.
Conclusions:
- hPSC-CMs offer a valuable reductionist model for studying non-genetic cardiac diseases.
- Further research and publication are needed to balance the representation of cardiac disease models.
- Addressing this gap is crucial for understanding and treating common heart conditions.
Abstract:
Non-genetic cardiac pathologies develop as an aftermath of extracellular stress-conditions. Nevertheless, the response to pathological stimuli depends deeply on intracellular factors such as physiological state and complex genetic backgrounds. Without a thorough characterization of their in vitro phenotype, modeling of maladaptive hypertrophy, ischemia and reperfusion injury or diabetes in human pluripotent stem cell-derived cardiomyocytes (hPSC-CMs) has been more challenging than hereditary diseases with defined molecular causes. In past years, greater insights into hPSC-CM in vitro physiology and advancements in technological solutions and culture protocols have generated cell types displaying stress-responsive phenotypes reminiscent of in vivo pathological events, unlocking their application as a reductionist model of human cardiomyocytes, if not the adult human myocardium. Here, we provide an overview of the available literature of pathology models for cardiac non-genetic conditions employing healthy (or asymptomatic) hPSC-CMs. In terms of numbers of published articles, these models are significantly lagging behind monogenic diseases, which misrepresents the incidence of heart disease causes in the human population.
