Portal vein of Spix’s yellow-toothed cavy (Galea spixii Wagler, 1831) [PDF]

Biotemas, 2013
Spix’s yellow-toothed cavy is a rodent belonging to the Caviidae family. This paper, taking into account the lack of information in the literature, aims to describe the portal vein origin in Spix’s yellow-toothed cavy.

Steroidogenesis during prenatal testicular development in Spix’s cavy Galea spixii [PDF]

Reproduction, Fertility and Development, 2021
Spix’s cavy is a potentially good experimental model for research on reproductive biology and sexual development. The aim of the present study was to evaluate the ontogeny of the steroidogenic enzymes involved in testicular androgen synthesis during prenatal development.

Steroidogenesis during postnatal testicular development of Galea spixii [PDF]

Reproduction, 2017
Abstract The androgen/estrogen balance is essential for normal sexual development and reproduction in mammals. Studies performed herein investigated the potential for estrogen synthesis in cells of the testes of a hystricomorph rodent, Galea spixii. The study characterized the expression of the key enzymes responsible for estrogen and

Galea spixii embryos have potential to produce steroid hormones.

Animal reproduction, 2023
Estrogens and progestogens are hormones produced by maternal organs and it is required for recognition and maintenance of pregnancy. In addition, the embryo may also be a source. For this, the aim was to identify steroidogenic expression on Galea spixii embryos early in the embryonic period.

Ultrastructure of spermatogenesis in Spix's yellow-toothed cavy ( Galea spixii ) [PDF]

Reproduction, 2014
Abstract This was a pioneer study of the spermatogenic process from the onset of puberty in Spix's yellow-toothed cavies (SYC, Galea spixii) bred in captivity. The study aimed to characterize fine structure of spermatogenesis. Twelve testes from pubertal and post-pubertal SYC males were studied using transmission electron microscopy ...

Arterial Vascularization of the Base of the Brain in Galea (Galea spixii)

Acta Scientiae Veterinariae, 2017
Background: Galea (Galea spixii) are rodents which are especially distributed in the northeastern region of Brazil, and have economic importance as their meat is used as a source of protein by the regional population.  Currently, they have received attention from researchers in studies involving their morphology. Thus, seeking to contribute information
