Step by Step about Germ Cells Development in Canine

Animals, 2021
Primordial germ cells (PGCs) have been described as precursors of gametes and provide a connection within generations, passing on the genome to the next generation.

Germ cells [PDF]

Current Opinion in Genetics & Development, 1999
Recently, cell signaling has been shown to be required for the formation of germ cells in the mouse embryo, direct observation of germ cell migration in living mouse embryos has been achieved, novel genes that control germ-cell migration have been identified in Drosophila, and the roles of many components of germ plasm in several species have become ...

Germ cell dynamics during nest breakdown and formation of the primordial follicle pool in the domestic turkey (Meleagris gallopavo)

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 ...

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

PLoS 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.

The dynamic expression of SOX17 in germ cells from human female foetus and adult ovaries after specification

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

Seasonal composition of immature germ cells in the Yesso scallop identified by vasa-like gene (my-vlg) and protein expression, with evidence of irregular germ cell differentiation accompanied with a high mortality event

Aquaculture Reports, 2021
The objective of this study was to understand germ cell renewal and differentiation in the Yesso scallop Mizuhopecten yessoensis throughout its reproductive cycle.

Effect of Mytomycin C Treatment on Feeder Cells and the Proliferation of Cultured Chicken Primordial Germ Cells Isolated from Embryonic Blood

The Journal of Poultry Science, 2001
Chicken primordial germ cells isolated from embryonic blood were cultured in vitro on feeder cells derived from the gonads of 7-day incubated embryos. Primordial germ cells were proliferated about 13 times during the 4 day culture period on the feeder ...

Germ cells in the teleost fish medaka have an inherent feminizing effect. [PDF]

PLoS Genetics, 2018
Germ cells are the only cells that can transfer genetic materials to the next generation via the sperm or egg. However, recent analyses in teleosts revealed another essential role of germ cells: feminizing the gonads.

Germ Cell Derivation from Pluripotent Stem Cells for Understanding In Vitro Gametogenesis

Cells, 2021
Assisted reproductive technologies (ARTs) have developed considerably in recent years; however, they cannot rectify germ cell aplasia, such as non-obstructive azoospermia (NOA) and oocyte maturation failure syndrome. In vitro gametogenesis is a promising

Tre1, a G protein-coupled receptor, directs transepithelial migration of Drosophila germ cells.

PLoS Biology, 2003
In most organisms, germ cells are formed distant from the somatic part of the gonad and thus have to migrate along and through a variety of tissues to reach the gonad.
