Such comparisons will help scientists to better understand this lone example of mammalian heart regeneration, and may ultimately lead to better drugs for treating injury and disease. (scientificamerican.com)
In a paper published in the March 25, 2010 issue of Nature, researchers working at the Salk Institute for Biological Studies and the Center of Regenerative Medicine in Barcelona (CMRB) identified a fish heart cell population that is the source of this astonishing healing feat, a finding that could provide insight into how mammalian hearts might be coaxed into repairing themselves after injury brought on by heart attack.
