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 ...

As part of their study, published in Developmental Cell, the research team followed the early development of the heart's muscular structures, called trabeculae, in zebrafish.

As part of their study, published today in Developmental Cell, the research team followed the early development of the heart’s muscular structures, called trabeculae, in zebrafish. Zebrafish ...

The heart’s “mini-brain” is independent and highly localized, according to researchers at the Karolinska Institutet in Stockholm, Sweden. The findings could lead to new research into ...

To see the heart develop in real time, the team turned to the Crick’s aquatic facility, home to the zebrafish that are used to study early development. ”Zebrafish hearts are very similar to ours in ...

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 ...

Zebrafish protein unlocks dormant genes for heart repair Date: January 2, 2025 Source: Hubrecht Institute Summary: Researchers have successfully repaired damaged mouse hearts using a protein from ...
