Scientists have shown for the first time that the blueprint for the four chambers of the human heart exists in the humble zebrafish, a study in eLife reports. The discovery provides key insights ...

The zebrafish is an ideal model organism to study the development of vertebrate-specific organs, such as the heart, because it is amenable to both loss-of-function and gain-of-function analyses.

Scientists at the Hubrecht Institute in the Netherlands have achieved a remarkable breakthrough in heart regeneration therapy ...

Additionally, scientists often conduct experiments with zebrafish, which have unique regenerative abilities. In the newest study, scientists looked at the progression of heart development in zebrafish ...

She was part of a small group of scientists working to establish zebrafish as a new model organism, hoping to use these small, shimmery fish to probe questions about the development of vertebrate ...

Zebrafish have an adaptive immune system that comprises both T and B cells. The molecular pathways that regulate the development and maturation of these lymphoid-cell populations have been highly ...

Artistic representation of heart ... zebrafish but not in mice. This showed us that Hmga1 plays a key role in heart repair.” Typically, the Hmga1 protein is important during embryonic ...

Cardiovascular diseases, such as heart attacks, are a leading cause of death worldwide resulting from a limited self-healing power of the heart. Unlike humans, zebrafish have the remarkable ...

Unlike humans, zebrafish ... a key role in heart regeneration in zebrafish. The Hmga1 gene is present in mice and humans too, and the Hmga1 protein is important during embryonic development ...

However, a recent study from a Max Delbrück Center for Molecular Medicine research team has found that zebrafish can regenerate cells and organs — even the heart. Under a microscope, researchers held ...

Studies of zebrafish have contributed significantly to our understanding of heart development, and Dr Guerra and colleagues used this organism to explore whether there were differences in ...
