@realdiscoveryfilm: Your body rebuilds liver, bone, skin, muscle. Not your heart. A zebrafish rebuilds its entire damaged heart in 60 days. No scar. A Dutch lab found the difference; a protein called Hmga1. And the gene for it is in you. It built your heart before you were born, then switched off. They turned it back on in mice. The muscle repaired. Real Discovery. What you were not told. #realdiscovery #heartregeneration #hearthealth #hiddennews #Science
