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.

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 ...

Red blood cells are essential for carrying oxygen throughout the body. In this study, zebrafish embryos exposed to polystyrene nanoparticles showed an increase in immature RBCs and a decrease in ...

Zebrafish, with their transparent bodies ... the system allows for high-resolution imaging of organs such as the heart, brain, and liver. The computer-vision-based control ensures precise ...

In this study, using zebrafish as a model organism, the researchers discovered that Wdr5 functions as a genomic guardian by regulating a specific epigenetic mark—H3K4 methylation. When Wdr5 was ...

In vertebrate retinas, specialized photoreceptors responsible for color vision (cone cells) arrange themselves in patterns ...

As a vertebrate, the zebrafish possesses many genes that perform the same or similar functions in mammals and therefore also in humans. Approximately 70 percent of zebrafish genes are also present in ...

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 ...
