Insights
Strategies to mature human induced pluripotent stem cells into cardiac cells (hiPSC-CMs) are reviewed. Improving hiPSC-CM metabolism is key for developing accurate models of heart disease and for drug screening.
Area of Science:
- Cardiology
- Stem Cell Biology
- Metabolic Research
Background:
- Human induced pluripotent stem cells (hiPSCs) are valuable for modeling human cell types.
- hiPSCs can differentiate into cardiac cells (hiPSC-CMs), crucial for cardiac pathophysiology studies.
- Current hiPSC-CMs exhibit fetal, not adult, characteristics, limiting their utility.
Purpose of the Study:
- To review strategies for promoting metabolic maturation of hiPSC-CMs.
- To identify methods for enhancing hiPSC-CMs to resemble adult cardiomyocytes.
- To enable patient-specific cardiac disease modeling and drug screening.
Main Methods:
- Review of culture medium compositions.
- Analysis of extended culture times.
- Evaluation of 3D culture techniques.
Main Results:
- Identified key strategies in culture media, duration, and 3D methods to promote hiPSC-CM maturation.
- Highlighted the critical role of metabolism in achieving an adult cardiac cell phenotype.
- Emphasized the need for standardized protocols.
Conclusions:
- Metabolic maturation is essential for hiPSC-CMs to serve as accurate models of adult cardiomyocytes.
- Standardized protocols are needed for reliable patient-specific disease modeling and drug discovery.
- Optimized hiPSC-CMs hold promise for advancing cardiac research and personalized medicine.
Abstract:
Human induced pluripotent stem cells (hiPSCs) are widely used in basic research because of their versatility and ability to differentiate into multiple cell types. In particular, differentiating hiPSCs into cardiac cells (hiPSC-CMs) has been an important milestone in cardiac pathophysiology studies. Although hiPSC-CMs offer a model for human cardiomyocytes, they still exhibit characteristics linked to the fetal cardiac cell phenotype. One important feature that prevents hiPSC-CMs from being identified as adult cells relates to their metabolism, which is a key factor in defining a mature phenotype capable of sustaining the workload requirements characteristic of fully differentiated cardiomyocytes. This review aims to present the most relevant strategies in terms of culture medium composition, culture times, and 3D culture methods that have been developed to promote the metabolic maturation of hiPSC-CMs, which are now widely used. Defining a standardized and universally accepted protocol would enable the creation of a cellular model for studies of cardiac pathophysiology from a patient-specific perspective and for drug screening.
