原文开头
Mechanical forces in the heart prevent tumor expansion in mice Wyatt G. Paltzer1 and James F. Martin1,2,3,4 H eart cancer is very rare in mammals (1). Moreover, the healthy adult heart does not regenerate. Human heart cells (cardiomyocytes) renew at an ~1% rate per year (2). The high mechanical load placed on cardiac tissue, which must overcome strong resistance to pump blood to all body organs, has been proposed to inhibit cardiomyocyte proliferation (3, 4). Indeed, reducing the mechanical load on the heart promotes the expression of cell cycle markers in cardiomyocytes of patients whose hearts were unloaded by a ventricular assist device (5). On page 387 in this issue, Ciucci et al. …
