This editorial refers to Cardiomyocyte proliferation and protection against post-myocardial infarction heart failure by cyclin D1 and Skp2 ubiquitin ligase by Tamamori-Adachi et al.,11 pp. 181–190, this issue.

A fundamental tenet in cardiac biology, namely that the heart is a postmitotic organ incapable of regeneration, has recently been challenged. According to the traditional belief, the number of cardiac myocytes we are born with is all we will have for the rest of our lives. If myocytes die (e.g. as the result of infarction), they cannot be renewed. This is why myocardial infarction (MI) and its consequences, such as congestive heart failure, continue to be a major cause of death worldwide despite the considerable therapeutic advances that have been made over the past decades.
In one attempt to evade this dilemma, cell replacement strategies are currently being investigated for their therapeutic potential to restore cardiac function. Indeed, a growing body of evidence from both basic animal studies and
