Porcine Germ Cells Phenotype during Embryonic and Adult Development

open access: yesAnimals, 2023
Primordial germ cells (PGCs) are the precursors of gametes. Due to their importance for the formation and reproduction of an organism, understanding the mechanisms and pathways of PGCs and the differences between males and females is essential. However, there is little research in domestic animals, e.g., swine, regarding the epigenetic and pluripotency

Cripto: Expression, epigenetic regulation and potential diagnostic use in testicular germ cell tumors [PDF]

open access: yes, 2016
Type II germ cell tumors arise after puberty from a germ cell that was incorrectly programmed during fetal life. Failure of testicular germ cells to properly differentiate can lead to the formation of germ cell neoplasia in situ of the testis; this ...

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.

To Be or Not to Be a Germ Cell: The Extragonadal Germ Cell Tumor Paradigm

open access: yesInternational Journal of Molecular Sciences, 2021
In the human embryo, the genetic program that orchestrates germ cell specification involves the activation of epigenetic and transcriptional mechanisms that make the germline a unique cell population continuously poised between germness and pluripotency.

Metastatic Mature Teratoma and Growing Teratoma Syndrome in Patients with Testicular Non-Seminomatous Germ Cell Tumors

open access: yesKorean Journal of Radiology, 2021
Metastatic mature teratoma is a common radiologic and histopathologic finding after chemotherapy for metastatic non-seminomatous germ cell tumors. The leading theory for these residual tumors is the selective chemotherapy resistance of teratomas versus ...

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.

Clinicopathological Features, Prognostic Factors, Survival Trends, and Treatment of Malignant Ovarian Germ Cell Tumors: A SEER Database Analysis

open access: yesOncology Research and Treatment, 2021
Objective: The aim of this study was to investigate the clinicopathological prognostic factors of malignant ovarian germ cell tumors (MOGCT) and evaluate the survival trends of MOGCT by histotype. Methods: We extracted data on 1,963 MOGCT cases diagnosed

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 ...

The histologic features of intratubular germ cell neoplasia and its correlation with tumor behavior [PDF]

open access: yesInvestigative and Clinical Urology, 2016
Purpose: To assess the prevalence of intratubular germ cell neoplasia (ITGCN) in patients with concurrent testis tumor and its correlation with histologic features and serum tumor markers.

Testicular germ cell tumors arise in the absence of sex-specific differentiation.

open access: yesDevelopment, 2021
In response to signals from the embryonic testis, the germ cell intrinsic factor NANOS2 coordinates a transcriptional program necessary for the differentiation of pluripotent-like primordial germ cells toward a unipotent spermatogonial stem cell fate ...
