Summary
Cardiac tissue engineering needs genomic mapping to replicate heart niches for better regeneration and disease models. Innovations are advancing, but maturity and cell communication remain challenges for clinical translation.
Area of Science:
- Cardiovascular Research
- Regenerative Medicine
- Biotechnology
Background:
- Cardiac tissue engineering (TE) aims to replicate the heart's complex cellular and extracellular matrix (ECM) environment.
- Current TE approaches struggle to integrate genomic insights of cellular niches for precise replication.
- Challenges include achieving optimal maturity, functional multicellular crosstalk, vascularization, innervation, and immune integration.
Purpose of the Study:
- To review current understanding of cardiac cellular/ECM heterogeneity.
- To synthesize progress in recapitulating cardiac features using advanced TE methods.
- To provide a roadmap for future cardiac TE innovations.
Main Methods:
- Critical evaluation of existing literature on cardiac cellular and ECM heterogeneity.
- Synthesis of recent advancements in iPSC-derived models, biomaterials, and 3D bioprinting for cardiac constructs.
- Analysis of challenges and emerging innovations in precision cardiac TE.
Main Results:
- Cardiac TE innovations have advanced, but replicating the native heart's complexity remains difficult.
- Existing models often lack sufficient cellular maturity and functional multicellular crosstalk.
- Genomic mapping of cellular niches is crucial for replicating spatial organization and microniches.
Conclusions:
- Addressing cardiac cellular/ECM heterogeneity is key to improving TE platforms.
- Integrating genomic data with advanced TE techniques can enhance cardiac regeneration and disease modeling.
- A roadmap is proposed to guide future research towards clinically transformative cardiac TE solutions.
