UC Berkeley and Caltech researchers identified a gene circuit in zebrafish that allows heart regeneration after injury. Using ...

Researchers have successfully repaired damaged mouse hearts using a protein from zebrafish. They discovered that the protein Hmga1 plays a key role in heart regeneration in zebrafish. In mice ...

The human heart beats 60-100 times a minute, without you needing to pay any attention to it. Heart function is controlled by the brain’s autonomic nervous system (the parasympathetic and ...

A heart attack will leave a permanent scar on a human heart, yet other animals, including zebrafish, can clear cardiac scar tissue and regrow damaged muscle as adults. Biologists sheds new light ...

An MDC research team led by Jan Philipp Junker and Daniela Panáková has found that zebrafish can regenerate heart tissue after injury. Connective tissue cells play an important role in the ...

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 learn more about what causes congenital heart defects, scientists often study embryonic heart development: looking at how the heart develops to understand what goes wrong and identifying what ...

An adult zebrafish heart is about 1 millimeter across, or roughly 13 times larger than the width of a human hair. But at the larval stage shown in this video, the heart is only about 250 micrometers ...

Zebrafish heart 60 days after injury showing the structure of the heart muscle cells have completely regenerated. [Phong Nguyen, copyright Hubrecht Institute.] Researchers from the group of Jeroen ...

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 ...

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). Red ...
