So University of Utah biologists, led by assistant professor Jamie Gagnon, tackled the problem by comparing two fish species: zebrafish, which can regenerate its heart, and medaka, which cannot.

Researchers, policymakers, and innovators around the world are taking steps to tackle the problem at its source. Scientists ...

To monitor the spatiotemporal organization of the heart in real time, the researchers turned to the humble zebrafish. Zebrafish fertilize their eggs externally and rapidly develop transparent embryos ...

Duke Distinguished Professor of Regenerative Biology in the Duke School of Medicine, who discovered heart regeneration in zebrafish two decades ago and has been studying it since. “But it’s just ...

The zebrafish is a good research stand-in for its fellow vertebrate, the human, because the two have many parts in common: brain, heart, liver, kidneys. And genome sequencing has shown that 84 ...

However, microscopic imaging revealed subtle effects, including increased eye distance and an elevated heart rate. To investigate further, the team compared the cell populations of control and ...

Zebrafish (Danio rerio) is a small freshwater fish that is an extensively studied vertebrate model organism. It can be bred rapidly in large numbers, is amenable to genetics, and has a clear ...

In zebrafish there are four types: red, green, blue, and UV cone cells. The cone mosaic refers to the highly organized spatial arrangement of these different cone types across the surface of the ...

Zebrafish are unassuming and undemanding. Almost every child knows that – at least any child that has kept fish in an aquarium. Since the beginning of the 20th century, these fish have been one of the ...
