The need for heart transplants will always exceed the number of donor hearts available for transplant. Thanks to research just out from Massachusetts General Hospital, though, this may not continue to be a problem for much longer. Researchers there have just succeeded in growing fully contractile heart tissue by recellularizing a collagen scaffold, and they’re hoping to refine the method so that it can be used as a “functional myocardial patch” for cardiac injuries.

D’un point de vue physiologique, le noyau pulpeux, la partie centrale des disques intervertébraux, est le premier touché. Il est composé en grande partie d’eau, ce qui lui confère ses propriétés d’amortisseur. Avec l’âge, les cellules pulpeuses deviennent progressivement moins prolifératives, plus sujettes à l’apoptose et incapables de produire cette fameuse matrice extracellulaire très hydratée.
