A case report of recurrent testicular germ cell tumor in a patient with a history of primary pulmonary germ cell tumor and a review of the literature

Frontiers in Oncology
BackgroundCompared to testicular germ cell tumors, the incidence of extragonadal germ cell tumors (EGCTs) is relatively low. While the lungs are a common site for metastasis of malignant germ cell tumors, primary pulmonary germ cell tumors are extremely ...

Embryonic Stem Cells and the Germ Cell Lineage

, 2011
Stem cells possess the unique ability to either propagate by self-renewal or to differentiate to mature tissues under the influence of appropriate molecular cues. This remarkable feature, also termed “stem cell potency” has been the focus of both a historical and current research spotlight on stem cells, and particularly the potential for human stem ...

In vitro derivation of germ cells from embryonic stem cells

Frontiers in Bioscience, 2010
Embryonic stem cells (ESCs) have the potential to differentiate into cells of all tissue types, as demonstrated by their capability to contribute to the development of all germ layers in chimeras and to form teratomas. Of interest, however, is the lack of evidence of gametogenic gonadal tissues within teratomas, such as testicular tubules or follicles.
