The skeleton, tendons, and glands of a functional jaw all derive from the same population of stem cells, ... To understand the role of Nr5a2, the scientists created zebrafish lacking this gene.

The NIH zebrafish image, which was taken to understand lymphatic vessel development in the brain, merges 350 individual images to reveal a juvenile zebrafish with a fluorescently tagged skeleton ...

UC Berkeley and Caltech researchers identified a gene circuit in zebrafish that allows heart regeneration after injury. Using ...

Zebrafish brains may only have 500 neurons, but they're still a scientific wonder. Get the Popular Science daily newsletter💡 Breakthroughs, discoveries, and DIY tips sent every weekday. Email ...

If a zebrafish’ spine is injured, the damaged neurons respond by dramatically changing their cellular functions. They take on a new and central role in orchestrating the very precise events that ...

Zebrafish with mutations in these proteins end up with curved spines, mimicking what's seen in people with scoliosis. The team reported their findings Dec. 1 in the journal eLife.

Zebrafish share up to 70% of genes with humans, which are easy to modify in the laboratory, and they are transparent, so their muscles are easily observed under a microscope.

At the same time, after analyzing several molecular biomarkers of neuroinflammation, damage, and recovery of neurons, scientists were convinced that, unlike mammals, zebrafish are capable of full ...
