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 ...

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 ...

The quantification of testicular cells during the postnatal development in two Caviomorph rodents: The guinea pig (Cavia porcellus) and the cutia (Dasyprocta agouti)
(2017-07-01)
The germinative, Sertoli and Leydig cells of two caviomorph rodents (Cavia porcellus and Dasyprocta agouti) were counted as well as the estimation of the total volume of the testis and the total volume of seminiferous ...
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 ...
Germination, Carbohydrate Composition and Vigor of Cryopreserved Caesalpinia echinata Seeds
(INST TECNOLOGIA PARANACURITIBA-PARANA, 2012)
The present study investigated the germination and vigor of Caesalpinia echinata (Brazilwood) seeds stored at negative temperatures. Recently harvested seeds were cryopreserved at -18 degrees or -196 degrees C and periodically ...
