摘要：
Cyclin A2 (CCNA2) has been identified as a key regulator that can induce cytokinesis in adult human cardiomyocytes, presenting a novel approach for cardiac regeneration. The study demonstrates that CCNA2 not only promotes cell division but also preserves the structural integrity of cardiomyocytes, suggesting its potential as a gene therapy for heart disease. This research highlights the reactivation of developmental gene programs, indicating a promising pathway for enhancing cardiac repair mechanisms in adults, which could significantly impact future therapeutic strategies for heart conditions.
