It is generally agreed that adult heart muscle cells (cardiomyocytes) cannot regenerate after an ischemic attack. However, Cui et al. (read HERE) in an experimental study in mice (read our articles on heart treatments in animals), found that their cardiomyocytes respond differently according to their age, regenerating better in younger hearts, although this capacity for regeneration is lost with age.

It is the first time to achieve heart cell regeneration and according to the authors, these findings may facilitate the development of new therapeutic strategies for patients with ischemic heart disease.
