Pure Embryonal Cell Carcinoma: A Rare Entity [PDF]

open access: yesJournal of Clinical and Diagnostic Research, 2023
Malignancy of the testes constitutes only one percent of all male cancers. Most testicular malignancies are Germ Cell Tumours (GCTs), which are broadly categorised into seminomatous and non-seminomatous types. Non seminomatous GCTs are further classified

Primary Germ Cell Tumors of the Mediastinum: 10 Years of Experience in a Tertiary Teaching Hospital

open access: yesKaohsiung Journal of Medical Sciences, 2005
Germ cell tumors occur mostly in the gonad. Extragonadal germ cell tumors are rare, and most occur in the retroperitoneum and mediastinum. Primary mediastinal germ cell tumors are often found in the anterior portion of the mediastinum and include ...

Embryonic Stem Cells: Testing the Germ-Cell Theory [PDF]

open access: yesCurrent Biology, 2011
The exact cellular origin of embryonic stem cells remains elusive. Now a new study provides compelling evidence that embryonic stem cells, established under conventional culture conditions, originate from a transient germ-cell state.

Transitioning from human primordial germ cells to embryonic germ cells

open access: yesStem Cell Reports
Primordial germ cells (PGCs) can give rise to pluripotent embryonic germ cells (EGCs) in rodents. Leitch and colleagues in this issue successfully derived human EGC-like cells from PGC-like cells and applied comprehensive multi-omic profiling to resolve their pluripotent and epigenetic dynamics, providing new insights into potential mechanisms ...

Entry of Mouse Embryonic Germ Cells into Meiosis

open access: yesDevelopmental Biology, 1997
Germ cells harvested from mouse embryonic genital ridges were mixed with disaggregated embryonic lung cells, and the reaggregates were cultured for 4-7 days. Germ cells derived from female embryos 10.5-13.5 days postcoitum (dpc) entered and progressed through meiotic prophase in vitro as in vivo, although with a 12- to 24-hr delay. If the cultures were

What is new about germ cell ovarian tumors?

open access: yes, 2022
Germ cell tumors of the ovary are the second most frequently found ovarian neoplasms following epithelial ovarian cancers. It is a heterogeneous group with an origin in a primitive germ cells.

AKT signaling promotes derivation of embryonic germ cells from primordial germ cells [PDF]

open access: yesDevelopment, 2008
Primordial germ cells (PGCs) are embryonic germ cell precursors. Although the developmental potency of PGCs is restricted to the germ lineage, PGCs can acquire pluripotency, as verified by the in vitro establishment of embryonic germ (EG) cells and the in vivo production of testicular teratomas.

Germ cells from mouse and human embryonic stem cells [PDF]

open access: yesReproduction, 2006
Abstract Mammalian gametes are derived from a founder population of primordial germ cells (PGCs) that are determined early in embryogenesis and set aside for unique development. Understanding the mechanisms of PGC determination and differentiation is important for elucidating causes of infertility and how endocrine disrupting ...
