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 ...

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 ...

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, ...

This rare glimpse into the beating heart of a zebrafish offers a view of how blood flows into and out of its heart. Zebrafish have a heart and a circulatory system similar to that of humans, but with ...

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 ...

Researchers have used zebrafish embryos to come up with a promising new therapy for kaposiform lymphangiomatosis – a rare, life-threatening genetic disorder of the lymphatic system.
