, 2012 The germline of Caenorhabditis elegans derives from a single founder cell, the germline blastomere P(4). P(4) is the product of four asymmetric cleavages that divide the zygote into distinct somatic and germline (P) lineages. P(4) inherits a specialized cytoplasm ("germ plasm") containing maternally encoded proteins and RNAs.

Of Stem Cells and Germ Cells [PDF]
Reproduction in Domestic Animals, 2011 ContentsStem cells have an intrinsic capacity to selfârenew and can differentiate to at least one specialized cell type. Different types of stem cells exist that can be culturedin vitro. The identity of the stem cells is marked by their origin and differentiation potential.

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

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 ...

Primary Culture System for Germ Cells from Caenorhabditis elegans Tumorous Germline Mutants
Bio-Protocol, 2017 The Caenorhabditis elegans germ line is an important model system for the study of germ stem cells. Wild-type C. elegans germ cells are syncytial and therefore cannot be isolated in in vitro cultures. In contrast, the germ cells from tumorous mutants can

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.

On the development of extragonadal and gonadal human germ cells
Biology Open, 2016 Human germ cells originate in an extragonadal location and have to migrate to colonize the gonadal primordia at around seven weeks of gestation (W7, or five weeks post conception).

Cell cycle regulation for meiosis in mammalian germ cells
The 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.

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
