Germ cells occupy a unique position in animal reproduction, development, and evolution. In
sexually reproducing animals, only they can produce gametes and contribute genetically to …

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 …

vasa is essential for germline development. However, the precise processes in which vasa
involves vary considerably in diverse animal phyla. Here we show that vasa is required for …

Fertility and gamete reserves are maintained by asymmetric divisions of the germline stem
cells to produce new stem cells or daughters that differentiate as gametes. Before entering …

Abstract Background The Pacific white shrimp (Litopenaeus vannamei) is the world's most
prevalent cultured crustacean species. However, the supply of high-quality broodstocks is …

Mesenchymal stem cells derived from bone marrow are a well characterized population of
adult stem cells that can be maintained and propagated in culture for a long time with the …

Understanding gonadal development in lampreys is complicated by their complex life cycle,
the long period during which their gonads remain histologically undifferentiated, and their …

Background The DAZ family genes boule, daz and dazl encode RNA binding proteins
essential for fertility of diverse animals including human. dazl has bisexual expression in …

Spermatogonial stem cells (SSCs) are the germline stem cells that are essential for the
maintenance of spermatogenesis in the testis. However, it has not been sufficiently …

The DAZ family genes boule, daz and dazl have conserved functions in primordial germ cell
(PGC) migration, germ stem cell proliferation, differentiation and meiosis progression. It has …
