Detection of Four Germ Cell Markers in Rats during Testis Morphogenesis: Differences and Similarities with Mice
(Karger, 2012-01-01)
Germ cells are the only cells capable of transmitting genetic information from generation to generation. Germ cell development has been widely studied in different species. Among mammals, the mouse is the model used in the ...
Characterization of &ITvasa&IT homolog in a neotropical catfish, Jundia (&ITRhamdia quelen&IT): Molecular cloning and expression analysis during embryonic and larval development
(Elsevier B.V., 2018-05-15)
We have characterized the full-length vasa cDNA from Jundia, Rhamdia quelen (Heptapteridae, Siluriformes). vasa encodes a member of the DEAD-box protein family of ATP-dependent RNA helicases. This protein is highly conserved ...
Epiblast embryo stem cells give origin to adult pluripotent cell populations: Primordial germ cell, pericytic and haematopoyetic stem cells. A review Las células madre del epiblasto dan origen a poblaciones de células pluripotentes adultas: Células germin
(Universidad de la Frontera, 2009)
Adult stem cells are great promise to the future of regenerative therapy, and understanding of its embryonic origin permit the discrimination of stem cell sources. Embryonic stem cells derived from inner cell mass of ...
Primordial germ cells (spermatogonial stem cells) of bullfrogs express sex hormone-binding globulin and steroid receptors during seasonal spermatogenesis
(2013-01-01)
In vertebrate species, testosterone seems to inhibit spermatogonial differentiation and proliferation. However, this androgen can also be converted, via aromatase, into estrogen which stimulates spermatogonial differentiation ...

Caracterización y Marcación de Células Germinales Primordiales
(Sociedad Chilena de Anatomía, 2016-06)
Primordial germ cells (PGC) are the precursors of oocytes and spermatocytes. They are characterized by being the only ones capable of accurately retaining pluripotent developmental ability after gastrulation. These cells ...
Sexual differentiation and primordial germ cell distribution in the early horse fetus
(Multidisciplinary Digital Publishing Institute, 2021-08)
It was the aim of this study to characterize the development of the gonads and genital ducts in the equine fetus around the time of sexual differentiation. This included the identification and localization of the primordial ...
Quantification of healthy and atretic germ cells and follicles in the developing and post-natal ovary of the South American plains vizcacha, Lagostomus maximus: evidence of continuous rise of the germinal reserve
(BioScientifica, 2013-11)
Female germ line in mammals is subjected to massive cell death that eliminates 60-85% of the germinal reserve by birth, and continues from birth to adult life until the exhaustion of the germinal pool. Germ cell demise ...
