Development of epididymis and vas deferens in Galea spixii: an ultrastructural view [PDF]

Journal of Morphological Sciences, 2016
AbstractThe study aimed to characterize the ultrastructure of components of the sperm pathway in Galea spixii (Spix's yellow-toothed cavy) at different stages of sexual development. Segments of the epididymis and vas deferens of 10 Galea spixii were studied using scanning and transmission electron microscopy.

Development of yolk sac inversion in Galea spixii and Cavia porcellus (Rodentia, Caviidae)

Placenta, 2012
Caviomorph development includes an inverted yolk sac. Since principle processes are not understood, we investigated its differentiation in Galea and re-examined material from the guinea pig. Galea showed the typical caviomorph conditions in blastocyst development and the nature of the definitive yolk sac, formed of the visceral layer that became ...

Development of spermatogenesis in captive-bred Spix’s yellow-toothed cavy (Galea spixii)

Reproduction, Fertility and Development, 2012
The aim of this study was to evaluate the phases of sexual development and spermatogenesis of Spix’s yellow-toothed cavy (Galea spixii) based on analyses of the structural components of the testes. The testes of animals from 0 to 150 days of age were collected by orchiectomy, weighed, and processed for analysis by light microscopy.

Follicular development and morphological changes in the vaginal epithelium during the estrous cycle of Galea spixii

Microscopy Research and Technique, 2016
AbstractThe current study aimed to determine if characteristics observed in vaginal cytology during the estrous cycle of female SYT cavies corresponded with proliferation of the vaginal epithelium, characterized by proliferating cell nuclear antigen (PCNA) immunolocalization, and with follicular development at different phases of the estrous cycle ...

Morphohistometric and steroidogenic parameters during testicular and epididymal differentiation in cavy (Galea spixii) fetuses

Reproductive Biology
Sexual differentiation and steroidogenic mechanisms have an important impact on postnatal gonadal phenotypic development. Thus, establishing the activities that lead to male phenotypic development can provide a better understanding of this process.

68 STEROIDOGENIC CONTROL OF INTRAUTERINE SEXUAL DIFFERENTIATION IN SPIX’S YELLOW-TOOTHED CAVY, GALEA SPIXII

Reproduction, Fertility and Development, 2015
The Spix’s yellow toothed (SYT) cavy is a species of rodent that lives in Caatinga vegetation of northeast Brazil. The SYT is utilised as a protein source by inhabitants of that region and has zootechnic potential. SYT cavies have been bred in captivity for studies related to reproductive biology.
