Key result

Review outlines cardiac myofibril assembly principles and recent findings on maintenance and turnover.

Why the study?

The assembly of actin and myosin into the paracrystalline arrangement of myofibrils in striated muscle has long puzzled cell biologists, prompting evolving models from cultured cells to iPSC-CMs.

Key Points

To review historical models and modern insights into the assembly, maintenance, and turnover of myofibrils in cardiac muscle.
Synthesized findings from three decades of research using cultured cardiomyocytes, embryonic heart tissues in situ, and human induced pluripotent stem cell-derived cardiomyocytes (iPSC-CMs).
Evaluated the impact of modern functional tools, including gene editing and super-resolution microscopy, on resolving myofibrillogenesis models.
Outlines the sequential transition of actin and myosin filaments into highly organized, paracrystalline myofibrillar structures within striated cardiac muscle.
Highlights a shift from observational models toward targeted functional analyses of myofibril repair, protein turnover, and structural maintenance.
