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 on ...

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

A cross-department collaboration headed by researchers at Harvard Medical School and Harvard University has witnessed the moment at which cells in the zebrafish embryo heart start beating in unison ...

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 ...

An uninjured (left) and injured adult zebrafish heart with neural crest cells labeled magenta. Note the neural crest cells activated around the edge of the injury in preparation for regenerating 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 arrhythmia, ...

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 ...

Could zebrafish hold the key to helping people who suffer heart attacks? Possibly, according to Duke University Medical Center scientists who studied the tropical fish and their "amazing" heart ...

Scientists have shown for the first time that the blueprint for the four chambers of the human heart exists in the humble zebrafish. Scientists have shown for the first time that the blueprint for the ...

One of the reasons coronary heart disease is so deadly is that fluid build-up and scarring can develop in the heart tissue. This prevents the heart from contracting properly, impacting its ability to ...
