Migration of germline progenitor cells is directed by sphingosine-1-phosphate signalling in a basal chordate. [PDF]

open access: yes, 2015
The colonial ascidian Botryllus schlosseri continuously regenerates entire bodies in an asexual budding process. The germ line of the newly developing bodies is derived from migrating germ cell precursors, but the signals governing this homing process ...

Cell cycle regulation for meiosis in mammalian germ cells

open access: yesThe Journal of Reproduction and Development, 2023
In mouse fetal gonads, germ cell development is accompanied by changes in cell cycle mode in response to external signals and intrinsic mechanisms of cells.

Role of β-catenin in post-meiotic male germ cell differentiation. [PDF]

open access: yesPLoS ONE, 2011
Though roles of β-catenin signaling during testis development have been well established, relatively little is known about its role in postnatal testicular physiology.

Identification of side population cells in mouse primordial germ cells and prenatal testis [PDF]

open access: yes, 2011
In mammals, the stem cells of spermatogenesis are derived from an embryonic cell population called primordial germ cells (PGCs). Spermatogonial stem cells displaying the "side population" (SP) phenotype have been identified in the immature and adult ...

SHISA6 Confers Resistance to Differentiation-Promoting Wnt/β-Catenin Signaling in Mouse Spermatogenic Stem Cells

open access: yesStem Cell Reports, 2017
In the seminiferous tubules of mouse testes, a population of glial cell line-derived neurotrophic factor family receptor alpha 1 (GFRα1)-positive spermatogonia harbors the stem cell functionality and supports continual spermatogenesis, likely independent

Piwi is required in multiple cell types to control germline stem cell lineage development in the Drosophila ovary. [PDF]

open access: yesPLoS ONE, 2014
The piRNA pathway plays an important role in maintaining genome stability in the germ line by silencing transposable elements (TEs) from fly to mammals.

Tre1 GPCR initiates germ cell transepithelial migration by regulating Drosophila melanogaster E-cadherin [PDF]

open access: yes, 2008
Despite significant progress in identifying the guidance pathways that control cell migration, how a cell starts to move within an intact organism, acquires motility, and loses contact with its neighbors is poorly understood.

Dnd knockout ablates germ cells and demonstrates germ cell independent sex differentiation in Atlantic salmon

open access: yesScientific Reports, 2016
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 problem.

DNA methylation and regulatory elements during chicken germline stem cell differentiation [PDF]

open access: yes, 2018
Funding for Open Access provided by the UMD Libraries' Open Access Publishing Fund.The production of germ cells in vitro would open important new avenues for stem biology and human medicine, but the mechanisms of germ cell differentiation are not well ...

A pilgrim's progress: Seeking meaning in primordial germ cell migration

open access: yesStem Cell Research, 2017
Comparative studies of primordial germ cell (PGC) development across organisms in many phyla reveal surprising diversity in the route of migration, timing and underlying molecular mechanisms, suggesting that the process of migration itself is conserved ...
