Conserved form and function of the germinal epithelium through 500 million years of vertebrate evolution
(Wiley, 2016-08)
The germinal epithelium, i.e., the site of germ cell production in males and females, has maintained a constant form and function throughout 500 million years of vertebrate evolution. The distinguishing characteristic of ...
Germ line Cysts and the Formation of the Germinal Epithelium During the Female Gonadal Morphogenesis in Cyprinus Carpio (Teleostei: Ostariophysi: Cypriniformes)
(Wiley-liss, 2010-09-01)
The formation of both germline cysts and the germinal epithelium is described during the ovary development in Cyprinus carpio. As in the undifferentiated gonad of mammals, cords of PGCs become oogonia when they are surrounded ...

Development of the germinal epithelium and early folliculogenesis during ovarian morphogenesis in the cichlid fish Cichlasoma dimerus (Teleostei, Perciformes)
(Wiley, 2014-10)
Formation of the germinal epithelium and folliculogenesis during ovarian development in Cichlasoma dimerus were described at the light- and electron-microscopic levels. Prior to gonadal differentiation, germ cells and ...
Cellular development of the germinal epithelium during the female and male gametogenesis of Chaetodon striatus (Perciformes: Chaetodontidae)
(2020-01-01)
SummaryButterflyfish Chaetodon striatus is highly sought after in the marine ornamental aquarium, although studies about its reproductive biology are scarce. Therefore, to contribute to a better understanding of the ...
Activity of the Ovarian Germinal Epithelium in the Freshwater Catfish, Pimelodus maculatus (Teleostei: Ostariophysi: Siluriformes): Germline Cysts, Follicle Formation and Oocyte Development
(Wiley-Blackwell, 2011-11-01)
Distinct types of oogonia are found in the germinal epithelium that borders the ovarian lamellae of Pimelodus maculatus: A-undifferentiated, A-differentiated and B-oogonia. This is similar to the situation observed for ...

Action of the Metalloproteinases in Gonadal Remodeling during Sex Reversal in the Sequential Hermaphroditism of the Teleostei Fish Synbranchus marmoratus (Synbranchiformes: Synbranchidae)
(Mdpi, 2018-05-01)
Teleostei present great plasticity regarding sex change. During sex reversal, the whole gonad including the germinal epithelium undergoes significant changes, remodeling, and neoformation. However, there is no information ...
