Germ cell markers in fishes - A review

open access: yesAquaculture and Fisheries, 2022
Identification of germ cell markers in fishes is crucial to track the germ cell differentiation and migration for manipulation of the cells to study sexual differentiation as well as to carry out transgenic transplantation techniques.

Transcription factor TFAP2C regulates major programs required for murine fetal germ cell maintenance and haploinsufficiency predisposes to teratomas in male mice. [PDF]

open access: yesPLoS ONE, 2013
Maintenance and maturation of primordial germ cells is controlled by complex genetic and epigenetic cascades, and disturbances in this network lead to either infertility or malignant aberration.

Spermatogenesis and sertoli cell activity in mice lacking Sertoli cell receptors for follicle stimulating hormone and androgen [PDF]

open access: yes, 2008
Spermatogenesis in the adult male depends on the action of FSH and androgen. Ablation of either hormone has deleterious effects on Sertoli cell function and the progression of germ cells through spermatogenesis.

Phase transitioned nuclear Oskar promotes cell division of Drosophila primordial germ cells

open access: yeseLife, 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.

Postnatal germ cell development in cryptorchid boys

open access: yesAsian Journal of Andrology, 2020
Cryptorchidism is associated with infertility in adulthood. Early orchiopexy is suggested to reduce the risk. Information is lacking on the potential link between infant germ cell maturation and the risk of future infertility.

Meiotic wave adds extra asymmetry to the development of female chicken gonads [PDF]

open access: yes, 2015
Development of female gonads in the chicken is asymmetric. This asymmetry affects gene expression, morphology, and germ cell development; consequently only the left ovary develops into a functional organ, whereas the right ovary remains vestigial.

Expression of Axolotl DAZL RNA, a Marker of Germ Plasm: Widespread Maternal RNA and Onset of Expression in Germ Cells Approaching the Gonad [PDF]

open access: yes, 2001
How germ cell specification occurs remains a fundamental question in embryogenesis. The embryos of several model organisms contain germ cell determinants (germ plasm) that segregate to germ cell precursors.

Migration of primordial germ cells during late embryogenesis of pikeperch Sander lucioperca relative to blastomere transplantation

open access: yesCzech Journal of Animal Science, 2017
Pikeperch Sander lucioperca is a valuable fish in Europe, and basic information about its embryonic development, especially primordial germ cell (PGC) migration, is important for use in biotechnology.

Expression of germ cell-less and Its Putative Regulatory Region in the Sea Cucumber, Apostichopus japonicus

open access: yesProgress in Fishery Sciences, 2023
The germ cell-less gene belongs to the BTB/POZ protein-family, whose structural domain plays an important role in the occurrence of mammalian gonads as it specifically combines with other DNA proteins. In this study, a unigene annotated as germ cell-less

LIN28 is selectively expressed by primordial and pre-meiotic germ cells in the human fetal ovary [PDF]

open access: yes, 2012
Germ cell development requires timely transition from primordial germ cell (PGC) self-renewal to meiotic differentiation. This is associated with widespread changes in gene expression, including downregulation of stem cell–associated genes, such as OCT4 ...
