Differentiation of primate primordial germ cell-like cells following transplantation into the adult gonadal niche

open access: yesNature Communications, 2018
Human embryonic stem cells can be differentiated in vitro into primordial germ cell-like cells (PGCLCs) that resemble early primordial germ cells (PGCs). Here the authors transplant PGCLCs generated from rhesus macaque iPSCs into mouse and rhesus macaque

PRDM14 is expressed in germ cell tumors with constitutive overexpression altering human germline differentiation and proliferation

open access: yesStem Cell Research, 2018
Germ cell tumors (GCTs) are a heterogeneous group of tumors occurring in gonadal and extragonadal locations. GCTs are hypothesized to arise from primordial germ cells (PGCs), which fail to differentiate.

Unraveling ovarian histology: The key morphological aspects that spur the development of the Fossa ovarii in equine

open access: yesThe Anatomical Record, EarlyView.
Abstract The equine ovary exhibits unique structural and developmental features that distinguish it from those of other domestic species, including the presence of an ovulation fossa and an inversion of cortical and medullary layers. This study aimed to investigate the morphostructural development of the equine fetal ovary, with particular emphasis on ...

Guidance of primordial germ cell migration [PDF]

open access: yesCurrent Opinion in Cell Biology, 2004
Primordial germ cells (PGCs), the progenitors of the gametes, migrate from the position where they are specified towards the region where the gonad develops. To reach their target, the PGCs obtain directional cues from cells positioned along their migration path.

Restoration of Genetic Resources from Ehime Native Chicken via Transferred Primordial Germ Cells (PGCs)

open access: yesThe Journal of Poultry Science, 2001
This experiment was designed to produce chimeric chicken by transferring primordial germ cells (PGCs) of Ehime native chicken embryos to White Leghorn ones.

Generation of germ cell-deficient pigs by NANOS3 knockout

open access: yesThe Journal of Reproduction and Development, 2022
NANOS3 is an evolutionarily conserved gene expressed in primordial germ cells that is important for germ cell development. Germ cell deletion by NANOS3 knockout has been reported in several mammalian species, but its function in pigs is unclear.

Determining the timeline of gonadal and genital differentiation in male and female equine fetuses allows for early detection and intervention in malformations

open access: yesThe Anatomical Record, EarlyView.
Abstract Sexual differentiation in the equine fetus involves coordinated morphogenetic processes that shape both the gonads and the genital ducts. Although the formation of testes and ovaries has been relatively well documented, the temporal dynamics and morphometric patterns of the mesonephric (Wolffian) and paramesonephric (Müllerian) ducts remain ...

Early stages of tooth development in the harbor porpoise Phocoena phocoena

open access: yesThe Anatomical Record, EarlyView.
Abstract Here we describe the stages of tooth development in toothed whales on the basis of the harbor porpoise (Phocoena phocoena). The aim of the study was to find out whether these stages are identical to those of other mammals analyzed so far although toothed whales are homodont and monophyodont.

Primordial germ cell specification from embryonic stem cells. [PDF]

open access: yesPLoS ONE, 2008
BACKGROUND: Primordial germ cell (PGC) specification is the first crucial step in germ line development. However, owing to significant challenges regarding the in vivo system, such as the complex cellular environment and potential problems with embryo ...

The Role of miRNAs in Chicken Immune Regulation and Prospects for Disease‐Resistant Breeding

open access: yesAnimal Research and One Health, EarlyView.
A schematic workflow illustrating the screening of disease‐resistant miRNAs and the generation of miRNA‐based disease‐resistant chickens via PGC‐mediated germline genome editing. ABSTRACT MicroRNAs (miRNAs) are emerging as pivotal regulators of the immune system, playing a decisive role in shaping disease resistance in chicken.
