Abstract:
AbstractPrimordial germ cells (PGCs) were isolated from the genital ridges of chicken (Gallus domesticus) embryos at the 19th stage and purified by Ficoll density-gradient centrifugation. PGCs were co-cultured with somatic cells in preliminary culture and subcultured. Identification of PGCs was carried out by histochemical methods, including alkaline phosphatase (AKP) and periodic acid–Schiff (PAS). The proliferating activity of PGCs in subculture was demonstrated by immunocytochemistry of proliferating cell nuclear antigen (PCNA). Meanwhile, proliferating PGCs were compared under different cu

Abstract:
We have isolated migrating primordial germ cells (PGCs) from 10.5-day mouse embryos and studied their behaviour when cultured on a mouse embryo fibroblast (STO) cell line. Living and fixed PGCs were identified by fluorescent labelling with a monoclonal antibody specific for PGCs in the culture system used. The behaviour of the cells was studied using interference reflexion microscopy (IRM) and time-lapse video cinematography. The IRM pattern displayed by PGCs is typical of highly motile cell types, the cells lack focal contacts and possess large areas of close contacts indicative of weak membr

Abstract:
The unique capability of germ cells to give rise to a new organism, allowing the transmission of primary genetic information from generation to generation, depends on their epigenetic reprogramming ability and underlying genomic totipotency. Recent studies have shown that genome-wide epigenetic modifications, referred to as “epigenetic reprogramming”, occur during the development of the gamete precursors termed primordial germ cells (PGCs) in the embryo. This reprogramming is likely to be critical for the germ line development itself and necessary to erase the parental imprinting and setting t

Abstract:
Primordial germ cells (PGCs), undifferentiated embryonic germ cells, are the only cells that have the ability to become gametes and to reacquire totipotency upon fertilization. It is generally understood that the development of PGCs proceeds through the expression of germ cell-specific transcription factors and characteristic epigenomic changes. However, little is known about the properties of PGCs at the metabolite and protein levels, which are directly responsible for the control of cell function. Here, we report the distinct energy metabolism of PGCs compared with that of embryonic stem cel

Abstract:
Nucleoporin 50 kDa (NUP50), a component of the nuclear pore complex, is highly expressed in male germ cells, but its role in germ cells is largely unknown. In this study, we analyzed the expression and function of NUP50 during the embryonic development of germ cells using NUP50-deficient mice. NUP50 was expressed in germ cells of both sexes at embryonic day 15.5 (E15.5), E13.5, and E12.5. In addition, NUP50 expression was also detected in primordial germ cells (PGCs) migrating into the genital ridges at E9.5. The gonads of Nup50−/− embryos of both sexes contained few PGCs at both E11.5 and E12

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. We categorized pikeperch embryonic development into six stages as in other fish species: zygote, cleavage, blastula, gastrula, segmentation, and hatching and described PGC migration. PGCs were visualized by injection of synthesized green fluorescent protein (GFP) within the 3’untranslated region (UTR) mRNA of nanos3.

Correlation of the number of primordial germ cells (PGCs) at stage 47 with the amount of germ plasm at the 8-cell stage and with the number of the germ-plasm-containing cells (GPCCs) was analysed using two different laboratory-raised colonies of Xenopus laevis, HD and J groups. The average number of PGCs in J group tadpoles was significantly larger than that in HD group tadpoles. The amount of germ plasm in J group embryos was also demonstrated to be larger than in HD group embryos. The amount of germ plasm was related positively to the number of GPCCs at the 8-cell stage and to the resulting

Abstract:
In most animals, primordial germ cells (PGCs) originate from an extragonadal region and migrate across the embryo to the gonads, where they differentiate and function. During their migration, PGCs move passively by morphogenetic movement of the embryo or move actively through signaling molecules. To uncover the underlying mechanism of first-phase PGC migration toward the germinal crescent in chickens, we investigated the spatial and temporal action of PGCs during primitive streak formation. Exogenously transplanted PGCs migrated toward the anterior region of the embryo and the embryonic gonads

Avian embryos have played an important role in the study of vertebrate development but further understanding of their development may also benefit the commercial poultry industry. Manipulation and use of primordial germ cells (PGCs) as a vehicle for constructed genotypes will be increasingly important for future improvement of commercial poultry including the turkey. However, the manipulation and use of PGCs will depend on a basic understanding of PGC migration. PGCs are known to migrate considerable distances before colonising the gonad.

Introduction: Germ cell tumors of the ovary include all neoplasm derived from primordial germ cells of the embryonal gonad. Five percent of germ cell tumors are malignant, representing three to five per cent of all ovarian carcinomas of which pure primary non-gestational ovarian choriocarcinoma accounts for less than one per cent of ovarian tumors. Primary choriocarcinoma of ovary could be gestational or nongestational in origin. They pose diagnostic challenges in reproductive age group patients because of elevated human chorionic gonadotrophin (hCG). Non-gestational choriocarcinoma (NGCO) is
