Rezultatele unui experiment anunţă o posibilă metodă de regenerare a ţesutului inimii umane. Injectarea unei proteine în sistemul vascular al şoarecilor de laborator a stimulat multiplicarea celulelor miocardice ale acestora după un infarct, îmbunătăţindu-le funcţiile cardiace. Până în prezent, un mic număr de noi celule musculare cardiace sunt create la vârsta adultă. Din cauza diminuării regenerării celulare, daunele provocate inimii de un infarct nu pot fi vindecate în mod natural.
