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 ...

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 ...

In combination, two commonly used heart drugs reverse fat accumulation in the liver, a study in animals has shown.

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 ...

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, ...

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 ...

Some animals have extraordinary healing powers to regrow their body parts including the heart. Here are eight.

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 sympathetic ...

A heart attack will leave a permanent scar on a human heart, yet other animals, including some fish and amphibians, can clear cardiac scar tissue and regrow damaged muscle as adults. Scientists have ...
