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 ...

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, ...

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 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 ...

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 ...

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 heart ...

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 ...

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 ...

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 ...

The zebrafish has emerged as a robust vertebrate model for studying cardiac electrophysiology and pharmacology, owing to its genetic tractability, optical transparency during early stages, and ...

It is already known that zebrafish can flexibly regenerate their hearts after injury. An international research group now shows that certain heart muscle cells play a central role in this process. The ...
