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 ...

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, ...

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 ...

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 ...

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 ...

Unlike humans, zebrafish can completely regenerate their hearts after injury. They owe this ability to the interaction between their nervous and immune systems, as researchers led by Suphansa ...

A recent study has compared zebrafish and medaka to figure out why zebrafish can regenerate heart tissue while medaka cannot, potentially advancing human cardiac arrest treatments. Researchers at the ...

Growing new cells is the holy grail for cardiologists. But this rare heart, frozen in time for 18 years in Sydney, held the ...
