Maturing human pluripotent stem cell-derived cardiomyocytes in human engineered cardiac tissues

Area of Science:

• Biomedical Engineering
• Stem Cell Biology
• Cardiovascular Research

Background:

• Significant progress has been made in engineering human engineered cardiac tissues (hECTs) using stem cell advancements.
• The field has shifted from animal-derived tissues to human-derived tissues in recent years.
• Current hECTs exhibit immature phenotypes compared to native adult myocardium.

Purpose of the Study:

• To review the maturation challenges in hECTs.
• To discuss the current state-of-the-art in hECT maturation.
• To explore future perspectives for hECTs in regenerative medicine, drug discovery, and preclinical testing.

Main Methods:

• Literature review focusing on cardiac tissue engineering and stem cell biology.
• Analysis of current methodologies for hECT generation and maturation.
• Synthesis of existing data on hECT phenotypes and functional properties.

Main Results:

• Human engineered cardiac tissues (hECTs) represent a significant advancement but lack adult-like maturity.
• Maturation remains a critical bottleneck for hECT applications.
• Various strategies are being explored to improve hECT maturation.

Conclusions:

• Maturing hECTs is essential for realizing their full potential in regenerative medicine, drug discovery, and disease modeling.
• Future research should focus on developing advanced maturation protocols.
• Overcoming the immaturity of hECTs will enable more accurate preclinical safety testing and pathophysiological studies.
