50 years of spermatogenesis: Sertoli cells and their interactions with germ cells
Biology of Reproduction, 2018 The complex morphology of the Sertoli cells and their interactions with germ cells has been a focus of investigators since they were first described by Enrico Sertoli. In the past 50 years, information on Sertoli cells has transcended morphology alone to

Prospects for transgenesis in the chick [PDF]
, 2004 Research to develop a useful method for genetic modification of the chick has been on-going since the first demonstrations in the mouse in the 1980s that genetic modification is an invaluable tool for the study of gene function. Manipulation of the chick

Poultry Science, 2020 This study determined, for the first time, the different subpopulations of germ cells and stereological changes within the cortex of the functional left ovary during germ cell nest breakdown, and formation of the primordial follicle pool in the domestic ...

Phase transitioned nuclear Oskar promotes cell division of Drosophila primordial germ cells
bioRxiv, 2018 Germ granules are non-membranous ribonucleoprotein granules deemed the hubs for post-transcriptional gene regulation and functionally linked to germ cell fate across species.

Effect of FSH on testicular morphology and spermatogenesis in gonadotrophin-deficient hypogonadal mice lacking androgen receptors [PDF]
, 2010 Follicle stimulating hormone (FSH) and androgen act to stimulate and maintain spermatogenesis. FSH acts directly on the Sertoli cells to stimulate germ cell number and acts indirectly to increase androgen production by the Leydig cells.

Frontiers in Endocrinology, 2023 BackgroundSOX17 has been identified as a critical factor in specification of human primordial germ cells, but whether SOX17 regulates development of germ cells after sex differentiation is poorly understood. MethodsWe collected specimens of gonadal ridge

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

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

DNA methylation and chromatin accessibility profiling of mouse and human fetal germ cells
Cell Research, 2016 Chromatin remodeling is important for the epigenetic reprogramming of human primordial germ cells. However, the comprehensive chromatin state has not yet been analyzed for human fetal germ cells (FGCs).
