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 ...

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 ...

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 ...

Scientists from Weizmann Institute and Sheba Medical Center says they were able to recreate rare lymphatic illness KLA in ...

Researchers from the group of Jeroen Bakkers, PhD, at the Hubrecht Institute, have shed new light on the remarkable capacity of the zebrafish to recover from cardiac damage and regenerate functional ...

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, ...

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 ...

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 ...

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 ...
