Epigenetic reprogramming in mouse primordial germ cells.

Mechanisms of Development, 2002
Genome-wide epigenetic reprogramming in mammalian germ cells, zygote and early embryos, plays a crucial role in regulating genome functions at critical stages of development. We show here that mouse primordial germ cells (PGCs) exhibit dynamic changes in

Early stages of tooth development in the harbor porpoise Phocoena phocoena

The 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.

Retention of paternal DNA methylome in the developing zebrafish germline

Nature Communications, 2019
Germ cells are the means of transferring genetic information to the next generation. Here the authors characterise the DNA methylomes of zebrafish primordial germ cells and find that, unlike mammals, the zebrafish germ cells do not undergo genome-wide ...

From primordial germ cells to primordial follicles: a review and visual representation of early ovarian development in mice

Journal of Ovarian Research, 2016
BackgroundNormal development of reproductive organs is crucial for successful reproduction. In mice the early ovarian developmental process occurs during the embryonic and postnatal period and is regulated through a series of molecular signaling events ...

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

Animal 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.

Cryopreservation of specialized chicken lines using cultured primordial germ cells

Poultry Science, 2016
Biosecurity and sustainability in poultry production requires reliable germplasm conservation. Germplasm conservation in poultry is more challenging in comparison to other livestock species. Embryo cryopreservation is not feasible for egg-laying animals,

Histological Characterization and Comparative Transcriptomic Analysis of Gonads During Early Sex Differentiation in the Northern Snakehead (Channa argus)

Animal Research and One Health, EarlyView.
This study delineates the early sex differentiation timeline in the northern snakehead (Channa argus). These findings provide a foundation for future sex‐control breeding in this economically important species. ABSTRACT The northern snakehead (Channa argus) is an economically important aquaculture species in China.

Discrete somatic niches coordinate proliferation and migration of primordial germ cells via Wnt signaling

Journal of Cell Biology, 2016
Mammalian primordial germ cells proliferate while migrating, but the mechanisms regulating these opposing processes remain unclear. Here, Cantú et al. show that somatic cell microenvironments modulate germ cell proliferation via canonical Wnt signaling ...

Follicle Stimulating Hormone in Cattle Breeding: Fundamentals, Innovations, and Scope

Animal Research and One Health, EarlyView.
FSH is crucial in cattle reproduction, with exogenous administration enhancing breeding and embryo production. Recombinant FSH offers advantages over pituitary‐extracted variants, including fewer injections, reduced stress, and safer production. These innovations improve breeding efficiency, optimize reproductive outcomes, and contribute to sustainable
