Biomaterials-Based Cell Therapy for Myocardial Tissue Regeneration

Area of Science:

• Biomedical Engineering
• Regenerative Medicine
• Cardiology

Background:

• Cardiovascular diseases (CVDs) are the leading global cause of mortality.
• Cardiac cell loss leads to dysfunction and increased mortality.
• Cell therapy offers a promising approach to replenish lost cardiac cells, particularly after ischemic events.

Purpose of the Study:

• To systematically review biomaterials-based cell therapy for myocardial tissue regeneration.
• To summarize key factors: cell sources, biomaterial components, and delivery systems.
• To provide an overview of in vivo cell tracking methods and future challenges.

Main Methods:

• Review of existing literature on cell therapy and biomaterials for cardiac repair.
• Systematic categorization of cell sources (somatic, stem, engineered cells).
• Classification of biomaterial components (natural, synthetic, electroactive) and delivery systems (patches, hydrogels, etc.).
• Inclusion of cell tracking techniques (MRI, fluorescence imaging).

Main Results:

• Biomaterials significantly improve cell retention and survival in cardiac cell therapy.
• Diverse cell sources and biomaterial compositions are available for myocardial regeneration.
• Various delivery platforms, including hydrogels and patches, are employed.
• Advanced imaging techniques enable in vivo monitoring of transplanted cells.

Conclusions:

• Biomaterials-based cell therapy is crucial for overcoming limitations of direct cell injection in treating CVDs.
• A comprehensive understanding of cell sources, biomaterials, and delivery methods is essential for effective myocardial regeneration.
• Future research should address current challenges to advance biomaterials-based cell therapy for cardiovascular health.
