Genetic Manipulation of Periostin Expression in the Heart Does Not Affect Myocyte Content, Cell Cycle Activity, or Cardiac Repair

Abstract excerpt

Following a pathological insult, the adult mammalian heart undergoes hypertrophic growth and remodeling of the extracellular matrix. Although a small subpopulation of cardiomyocytes can reenter the cell cycle following cardiac injury, the myocardium is largely thought to be incapable of significant regeneration. Periostin, an extracellular matrix protein, has recently been proposed to induce reentry of...
