Gli scienziati della Harvard Medical School di Boston sono riusciti a produrre in laboratorio un tessuto artificiale che "mima" i battiti del cuore.
Il tessuto è composto da un'impalcatura elastica costituita da materiali gelatinosi: essi contengono proteine naturali e grandi quantità d'acqua, proprio come molti tessuti dell'organismo umano.
Il materiale ottenuto dai ricercatori è stato in seguito sottoposto a tecniche di microingegneria, al fine di creare delle scanalature in cui allineare le cellule del muscolo cardiaco pronte a contrarsi in modo sincrono.
Le applicazioni sono legate all'obiettivo di creare dei veri e propri "cerotti pulsanti" in grado di riparare i danni provocati dall'infarto cardiaco.
