Forscher fanden heraus, dass die Fähigkeit eines geschädigten Herzens, neue Muskelzellen zu bilden, bis zu sechsmal größer ist als die eines gesunden Herzens. Der Mechanismus hinter diesem Effekt ist jedoch noch unbekannt und es gibt noch keine Hypothese, die ihn erklären könnte

>Researchers at Karolinska Institutet have now discovered that after an injury, the rate of cell renewal is even lower than in a healthy heart. Standard-of-care for patients with advanced heart failure is a surgically implanted pump that helps propel blood, a so-called left ventricular assist device (LVAD)

>Surprisingly, the researchers found that patients with such a heart pump, who have shown significant improvement in their heart function, can regenerate heart muscle cells at a rate more than six times higher than in healthy hearts.

>“The results suggest that there might be a hidden key to kick-start the heart’s own repair mechanism”, says Olaf Bergmann, senior researcher at the Department of Cell and Molecular Biology at Karolinska Institutet and last author of the paper.
>
>The mechanism behind the effect is still unknown and there is not yet any hypothesis to explain it.

Sounds ripe for yet another stem cell miracle cure.
