Fish, like many other animals, have two major cell lineages, namely the germline and soma.
The germ-soma separation is one of the earliest events of embryonic development. Germ …

Although present at relatively low number in the testis, spermatogonial stem cells (SSCs) are
crucial for the establishment and maintenance of spermatogenesis in eukaryotes and, until …

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 …

Genetic introgression of escaped farmed Atlantic salmon (Salmo salar) into wild populations
is a major environmental concern for the salmon aquaculture industry. Using sterile fish in …

The presence of germ cells in the early gonad is important for sexual fate determination and
gonadal development in vertebrates. Recent studies in zebrafish and medaka have shown …

No information exists on the identification of primordial germ cells (PGCs) in the super‐order
Protacanthopterygii, which includes the Salmonidae family and Atlantic salmon (Salmo salar …

Germ cell transplantation is a promising technology for the propagation of endangered or
valuable fishes. In this technique, sterile male and female recipient fish are injected with …

This review provides a general view on teleost germline development using primordial germ
cells (PGCs) or spermatogonia (SG), highlighting recent progress in research on these two …

Primordial germ cell (PGC) specification occurs early in development. PGC specifiers have
been identified in Drosophila, mouse, and human but remained elusive in most animals …

Sturgeons (chondrostean, acipenseridae) are ancient fish species, widely known for their
caviar. Nowadays, most of them are critically endangered. The sterlet (Acipenser ruthenus) …
