This rare glimpse into the beating heart of a zebrafish offers a view of how blood flows into and out of its heart. Zebrafish have a heart and a circulatory system similar to that of humans, but with ...

When a zebrafish heart is damaged, it can fully restore its function within 60 days. "We don't understand why some species can regenerate their hearts after injury while others cannot," explains ...

They discovered that the protein Hmga1 plays a key role in heart regeneration in zebrafish. In mice, this protein was able to restore the heart by activating dormant repair genes without causing ...

Researchers from the Bakkers group at the Hubrecht Institute have successfully repaired damaged mouse hearts using a protein from zebrafish. They discovered that the protein Hmga1 plays a key role in ...

Artistic representation of heart regeneration: Hmga1 in green symbolically flows from the border zone of a zebrafish heart (top right) to the injured border zone of a mouse heart (left).

Researchers from the Hubrecht Institute and their collaborators at other institutions have used a protein from zebrafish dubbed Hmga1 which plays a key role in heart regeneration, to reactivate ...
