• To achieve a higher level of maturation in engineered cardiac tissues, closely resembling adult human cardiac tissue.

Main Methods:

• Utilized stem-cell-derived cardiomyocytes.
• Developed and implemented a novel tissue engineering strategy.
• Focused on achieving structural and functional maturation.

Main Results:

• Successfully generated cardiac tissues with enhanced maturation.
• The engineered tissues exhibit characteristics closer to adult human myocardium.
• Demonstrated a significant improvement in cardiac tissue engineering.

Conclusions:

• The new strategy offers a promising approach for creating more physiologically relevant engineered cardiac tissues.
• This advancement holds potential for improving cardiac disease research and therapeutic development.
