In A Nutshell Egg geometry drives development: The curved shape of a zebrafish egg causes unequal cell divisions, creating larger cells near the animal pole and smaller cells at the margin—a size ...

When early cartographers undertook perilous expeditions to map unknown corners of the world with sextants, compasses, and hand-drawn diagrams, it’s unlikely they imagined that someday anyone with an ...

Life begins with a single fertilized cell that gradually transforms into a multicellular organism. This process requires precise coordination; otherwise, the embryo could develop serious complications ...

Researchers at the National Institutes of Health have published an atlas of zebrafish development, detailing the gene expression programs that are activated within nearly every cell type during the ...

Zebrafish eggs contain a sunscreen called gadusol that protects the growing embryo from harmful rays. The ultraviolet rays in sunlight are damaging. To shield against this, vertebrates produce a ...

Scientists have uncovered a new way embryonic cells divide when conventional mechanisms fail. Cell division underpins all ...

Molecular developmental biologists used zebrafish embryos to study a gene mutation that causes scoliosis, a sideways curvature of the spine that typically occurs in humans just before puberty. Popular ...

Popular in aquariums all over the world, the zebrafish is native to South Asia. But here in a Cincinnati Children's laboratory, the freshwater variant plays a vital role in scientific discovery. The ...
