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 ...

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 ...

When the human heart is damaged by a heart attack, stiff scar tissue eventually forms around the affected areas. This weakens the heart's pumping ability and increases the risk of heart failure and ...

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 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 ...

(Beyond Pesticides, June 30, 2023) Exposure to environmentally relevant concentrations of the herbicide glyphosate (GLY) has the potential to induce heart damage (cardiotoxicity) through the aging ...

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 ...

Researchers from the Bakkers group at the Hubrecht Institute have successfully repaired damaged mouse hearts using a protein from zebrafish. They discovered that the protein Hmga1 plays a key role in ...

Specifically, the researchers wanted to understand how a large group of cells works together to orchestrate a complex, tissue-wide activity like the first heartbeat. “The way most people have thought ...
