To be or not to be a germ cell: the extragonadal germ cell tumor paradigm [PDF]

open access: yes, 2021
In the human embryo, the genetic program that orchestrates germ cell specification in-volves the activation of epigenetic and transcriptional mechanisms that make the germline a unique cell population continuously poised between germness and pluripotency.

Molecular and epigenetic pathogenesis of germ cell tumors

open access: yesAsian Journal of Urology, 2021
The development of germ cell tumors (GCTs) is a unique pathogenesis occurring at an early developmental stage during specification, migration or colonization of primordial germ cells (PGCs) in the genital ridge.

LINEing germ and embryonic stem cells’ silencing of retrotransposons [PDF]

open access: yesGenes & Development, 2014
Almost half of our genome is occupied by transposable elements. Although most of them are inactive, one type of non-long terminal repeat (LTR) retrotransposon, long interspersed nuclear element 1 (LINE1), is capable of retrotransposition. Two studies in this issue, Pezic and colleagues (pp. 1410–1428) and Castro-Diaz and colleagues (pp.

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.

Treatment of clinical stage I non-seminoma

open access: yesAsian Journal of Urology, 2021
Germ cell cancers are the most common solid tumors among men between 15 and 40 years. Non-seminomatous germ cell tumors (NSGCTs) represent a unique and exclusive cohort of germ cell tumor patients. Non-seminoma can harbor different histologic components.

Management of germ cell tumors in children: Approaches to cure [PDF]

open access: yes, 2002
The introduction of cisplatinum chemotherapy and current advances in the surgical treatment have resulted in a dramatic improvement of the prognosis of children with malignant germ cell tumors (GCT).

Dysgerminoma with Embryonal Carcinoma, a Rare Ovarian Malignant Mixed Germ Cell Tumor in a 13-Year-Old Girl: A Case Report [PDF]

open access: yesMajallah-i Zanān, Māmā̓ī va Nāzā̓ī-i Īrān
Introduction: Pediatric patients rarely develop ovarian tumors, but mainly develop ovarian germ cell tumors. Malignant germ cell tumors are generally rare and dysgerminoma is the most frequent malignant ovarian neoplasm in young and adolescent girls.

A germ cell origin of embryonic stem cells? [PDF]

open access: yesDevelopment, 2005
Because embryonic stem (ES) cells are generally derived by the culture of inner cell mass (ICM) cells, they are often assumed to be the equivalent of ICM cells. However, various evidence indicates that ICM cells transition to a different cell type during ES-cell derivation.

Establishment of pluripotent cell lines from vertebrate species - Present status and future prospects [PDF]

open access: yes, 1999
Pluripotent embryonic stem (ES) cells are undifferentiated cell lines derived from early embryos and are capable of unlimited undifferentiated proliferation in vitro.

Chemotherapy-Induced Depletion of OCT4-Positive Cancer Stem Cells in a Mouse Model of Malignant Testicular Cancer

open access: yesCell Reports, 2017
Summary: Testicular germ cell tumors (TGCTs) are among the most responsive solid cancers to conventional chemotherapy. To elucidate the underlying mechanisms, we developed a mouse TGCT model featuring germ cell-specific Kras activation and Pten ...
