Fish biology has been developed for more than 100 years, but some important
breakthroughs have been made in the last decade. Early studies commonly concentrated on …

MicroRNAs (miRNAs) are small noncoding RNAs that extensively regulate gene expression
in animals, plants, and protozoa. miRNAs function posttranscriptionally by usually base …

The ability to define cell types and how they change during organogenesis is central to our
understanding of animal development and human disease. Despite the crucial nature of this …

Early embryonic development is driven exclusively by maternal gene products deposited
into the oocyte. Although critical in establishing early developmental programs, maternal …

Spermatogenesis is a developmental process during which a small number of diploid
spermatogonial stem cells produce a large number of highly differentiated spermatozoa …

Introgression of farmed salmon escapees into wild stocks is a major threat to the genetic
integrity of wild populations. Using germ cell-free fish in aquaculture may mitigate this …

The regulated migration of cells is essential for development and tissue homeostasis, and
aberrant cell migration can lead to an impaired immune response and the progression of …

Spermatogenesis is a fundamental process in male reproductive biology and depends on
precise balance between self-renewal and differentiation of male germ cells. However, the …

Over the last several decades zebrafish (Danio rerio) has become a major model organism
for the study of vertebrate development and physiology. Given this, it may be surprising how …

During development, functional structures must form with the correct three-dimensional
geometry composed of the correct cell types. In many cases cell types are specified at …
