Signaling at the crossroads of gonad development

Trends in Endocrinology and Metabolism, 2005
In mammals, the gonads arise as bipotential primordia that are capable of developing as either testes or ovaries. Expression of the Y-linked gene Sry in the XY gonad initiates testis differentiation; in the absence of Sry, ovarian pathways prevail. Although the molecular targets of SRY are not known, many of the early cellular and morphological events ...

Development of sexual dimorphism in the embryonic gonad

Human Genetics, 1981
Differentiation of gonads in embryonic pigs (ages 24 to 44 days) was studied by light and electron microscopy. Incipient short cord-like structures were seen in embryos of both sexes at the age of 24 days. The cords were ultrastructurally similar. Medullary cords appeared in the testis at 26 days and in the ovary at 28 days.

Development of the gonads in the female japanese quail

American Journal of Anatomy, 1968
AbstractThe germ cells in the Japanese quail, appear in the gonadal area between two to two and one half days incubation with a preferential distribution favoring the left gonad. Proliferation of the primary or medullary cords from the germinal epithelium was observed between four and five and one half days.

Morphological development of the gonads in zebrafish

Journal of Fish Biology, 2003
Gonadogenesis of zebrafish Danio rerio was investigated by means of light microscopy to test the suitability of gonad histology as an endpoint in hazard assessment of endocrine‐active compounds. At age 2 weeks post‐fertilization (pf), primordial germ cells were found in a dorsocaudal position in the body cavity. At 4 weeks pf, the majority of the fish (

Embryonic Development of the Porcine Indifferent Gonad and Testis

Journal of Veterinary Medicine Series A, 1991
SummaryThe early gonadal development in the pig from day 18 to day 36 post conception, when distinct testes were present in male embryos, has been studied. The development of the porcine gonad followed the general mammalian pattern. During testicular differentiation, the germ cells and the relevant somatic cells, the Sertoli cells, became enclosed in ...
