Zebrafish Regeneration.mov

When the zebrafish heart is damaged, the wound site is rapidly sealed with a fibrin clot that stems bleeding within seconds. Following clot formation, the tissue that surrounds the heart muscle—the epicardium—gradually covers the fibrin clot via migration and cell division. Over the next few months, new cardiac muscle is produced and replaces the clot. Growth factors, like FGF1, produced by the new heart tissue, signals the cells of the epicardial layer to migrate into the heart and form new blood vessels, to provide essential blood flow to the regenerating tissue. Over time, the wounded zebrafish heart returns to nearly its original shape, size, and pumping ability

We lost our Dad 29/01/11 due to a heart attack, little did we know he had heart disease, when he suffered his heart attack the left side of the muscle in his heart got completely damaged, and unfortunately as we know, dead heart muscle can't fully repair, after 8 days, my dad passed with us all by his side.

Please Help my sister raise money for The British Heart Foundation! and buy a hand made teddy! Please help BHF! Please.
