Although vertebrates display a superficial bilateral symmetry, most internal organs develop and locate with a consistent left:right asymmetry. There is still considerable debate as to when this process actually begins, but it seems that, at least for some species, the initial steps occur at a very early stage of development. In recent years, a number of model systems, including the chick embryo, have been utilised to increase our understanding of the molecular basis of this complex…

Meiotic wave adds extra asymmetry to the development of female chicken gonads

An updated model is proposed suggesting that the localization of germ cells—in the left or right gonad; in the cortex or medulla of the left Gonad; and in the central part or the extremities of theleft cortex—has direct consequences for their development and participation in adult reproduction.

The avian ovary and follicle development: some comparative and practical insights

This review focuses on recent research related to the avian ovary and, in particular, cellular mechanisms mediating embryonic growth of the ovary, postembryonic follicular development, and the

Gene expression profiling in embryonic chicken ovary during asymmetric development.

It is proposed that asymmetric expression of this cohort of genes (FSHR, CYP19A1, caspase 3, cospase 8) leads to the development of dimorphic gonads during embryogenesis.

Genetic Regulation of Avian Testis Development

This review describes the current understanding of avian testis development at the cell biology and genetic levels and identifies areas of future research on the genetics.

Sex Determination, Gonadal Sex Differentiation and Pl--asticity in Vertebrate Species.

This review outlines the current understanding of vertebrate SD and gonadal sex differentiation, and suggests that this is the ideal biological event that can make us understand the evolutionary conundrums underlying speciation and species diversity.

The cell biology and molecular genetics of Müllerian duct development

The Müllerian ducts are part of the embryonic urogenital system that serve a critical function in the transport and development of the oocyte and/or embryo and some questions remain to be answered at the molecular genetic level.

Oestrogen in the chick embryo can induce chromosomally male ZZ left gonad epithelial cells to form an ovarian cortex that can support oogenesis

It is found that CASI does not apply to chicken ovarian cortex development, and the gonadal epithelium responds to oestrogen via ERα and drives cortex formation independently of the medulla's phenotypic sex.

In the chick embryo, estrogen can induce chromosomally male ZZ left gonad epithelial cells to form an ovarian cortex which supports oogenesis

It is found that both female and male cells can become part of the cortical domain and that this can form relatively independently of the sex of the medulla as long as estrogen is provided, and it is shown that the cortex promoting activity of estrogen signalling is mediated via Estrogen Receptor alpha within the left gonad epithelium.

Estrogen suppresses DMRT1 expression during ovarian development in the chicken

Analysis of sex-reversed gonads and mixed-sex chimeric gonads, suggests that the reduction in DMRT1 protein is due to inhibition of D MRT1 expression by estrogen, and suggests that estrogen signalling is involved in primary sex determination by regulation of DMRt1 protein expression.



PITX2 controls asymmetric gonadal development in both sexes of the chick and can rescue the degeneration of the right ovary

It is shown that the chick gonads already have distinct morphological and molecular left-right (L-R) characteristics in both sexes at indifferent (genital ridge) stages and that these persist, becoming more elaborate during sex determination and differentiation, but have no consequences for testis differentiation.

Mechanism of asymmetric ovarian development in chick embryos

It is suggested that early asymmetric expression of PITX2 leads to asymmetric ovarian development through up- or downregulation of RALDH2, Ad4BP/SF-1, estrogen receptor α and cyclin D1.

Sexually Dimorphic and Sex-Independent Left-Right Asymmetries in Chicken Embryonic Gonads

Germ cell and pluripotency-associated genes show both sex-dependent and independent left-right asymmetry and a complex pattern of expression in both sexes.

Pitx2 regulates gonad morphogenesis

Observations indicate that the effects elicited by Pitx2 during the development of the female chick ovary are critical for cell topology, growth, fate, and ultimately organ morphogenesis and function.

The Molecular Genetics of Ovarian Differentiation in the Avian Model

This review discusses sexual differentiation in chicken embryos, with emphasis on ovarian development, and highlights genes that may play a conserved role in this process, and discusses how interaction between ovarian pathways may be regulated.

Somatic sex identity is cell-autonomous in the chicken

This study demonstrates that avian somatic cells possess an inherent sex identity and that, in birds, sexual differentiation is substantively cell autonomous and that the sex-determining mechanism in birds is investigated.

Mechanisms of gonadal morphogenesis are not conserved between chick and mouse.

Retinoic acid coordinates somitogenesis and left–right patterning in vertebrate embryos

It is reported that blocking the production of retinoic acid in chicken embryos leads to a desynchronization of somite formation between the two embryonic sides, demonstrated by a shortened left segmented region.
