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

The team then compared the activity of the Hmga1 gene in zebrafish, mice, and humans. In human hearts, as in adult mice, the Hmga1 protein is not produced after a heart attack.

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 ...

Researchers from the group of Jeroen Bakkers at the Hubrecht Institute have found that the muscle cells in the heart of zebrafish change their metabolism, the way in which they generate energy ...

The zebrafish heart comprises four chambers, like humans (though the chambers are very different). Neurons in the IcNS are concentrated near the valves between these chambers, particularly in an ...

Heart defects are the most common congenital defect, yet scientists still struggle to understand why they occur. A new study from the Max Delbruck Center for Molecular Medicine investigates a ...

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 ...

When a portion of a zebrafish's heart is removed, the dynamic interplay between a mass of stem cells that forms in the wound and the protective cell layer that covers the wound spurs the regeneration ...

Unlike humans, zebrafish grow new heart muscle cells: they have a regenerative capacity. When a zebrafish's heart is damaged, it can fully restore its function within 60 days.

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”, ...
