Germ cells undergo epigenome reprogramming for proper development of the next generation. The achievement of in vitro germ cell derivation from human and mouse pluripotent stem cells and further differentiation in a plane culture and in aggregation with gonadal somatic cells offers unprecedented opportunities for investigation of the germ cell ...

Current Opinion in Oncology, 1999
The publication of the proceedings of Fourth Workshop on Carcinoma in situ was an impressive leap in our understanding of the interaction between prenatal and postpubertal factors in the development of germ cell cancer as well as increased insight into the molecular events that are involved in the development of these tumors. From this work, physicians

Developmental arrest of germ cells in the pathogenesis of germ cell neoplasia
APMIS, 1998Clinical observations and epidemiological evidence suggest that important aetiopathological events that cause neoplastic transformation of the male germ cell may occur in fetal life or early infancy. The incidence of germ cell neoplasia is high in individuals with various disorders of gonadal development and sexual differentiation, such as gonadal ...

Immature germ cell conception—in vitro germ cell manipulation
Best Practice & Research Clinical Endocrinology & Metabolism, 2000Experimental studies in laboratory animals have shown that successful conception can be achieved by fertilizing oocytes with immature male germ cells. This gave rise to the concept that immature germ cells recovered from the testes of azoospermic men with maturation arrest may be used for assisted reproduction.

THE RADIOSENSITIVITY OF GERM CELLS
Biological Reviews, 1964SummaryThe radiosensitivity of germ cells depends on (a) the criterion by which it is assessed, and (b) the developmental stage at the time of irradiation. For any given parameter and cell‐type, the final effect exerted by ionizing radiations depends on the genetic make‐up and age of the organism; type of irradiation; method of irradiation (acute ...

Surface cells in adult ovaries represent germ line-competent embryonic stem cells. They are a novel type of totipotent progenitors for distinct cell types including female germ cells/oocytes, with the potential for use in the autologous treatment of ovarian infertility and stem cell therapy.

Science, 2017
Plant Biology Unlike animals, plants do not set aside a germline. Instead, germ cells are developed on demand from somatic lineages. Zhao et al. examined the regulatory pathways that manage the transition from somatic to germ cell development in the small plant Arabidopsis (see the Perspective by Vielle-Calzada).

Germ Cell Tumors (GCT) represent an important group of mediastinal tumors. Because of genetic characteristics and behavior have been divided in prepubertal and postpubertal tumors, and their origin remains controversial. The genetic changes are diverse, but the most frequent is i (12p), and can be associated to gonadal disgenesis.
