Gonad development: Signals for sex
نویسنده
چکیده
The formation of testes or ovaries in the mammalian embryo is critical in determining sexual identity and the ability to reproduce. Recent studies have begun to illuminate the cellular signalling events required for development of functional testes.

Signaling Pathways Involved in Mammalian Sex Determination and Gonad Development.
The development of any organ system requires a complex interplay of cellular signals to initiate the differentiation and development of the heterogeneous cell and tissue types required to carry out the organs' functions. In this way, an extracellular stimulus is transmitted to an intracellular target through an array of interacting protein intermediaries, ultimately enabling the target cell to ...
متن کاملFgf9 and Wnt4 Act as Antagonistic Signals to Regulate Mammalian Sex Determination
The genes encoding members of the wingless-related MMTV integration site (WNT) and fibroblast growth factor (FGF) families coordinate growth, morphogenesis, and differentiation in many fields of cells during development. In the mouse, Fgf9 and Wnt4 are expressed in gonads of both sexes prior to sex determination. Loss of Fgf9 leads to XY sex reversal, whereas loss of Wnt4 results in partial tes...
متن کاملI-43: Identification of SOX3 as an XX MaleSex Reversal Gene in Mice and Jumans
Background: Mammals utilise an XX/XY system of sex determination in which the Y-linked gene SRY (Sexdetermining region Y) exerts a dominant masculinising influence on sexual development. Sex chromosome homology and comparative sequence studies suggest that SRY evolved from the related SOX3 gene on the X chromosome, although there is no direct functional evidence to support this hypothesis. The ...
متن کاملPolygenic sex determination
What is sex determination? Sex determination is the mechanism by which sexual organisms direct gonad development towards distinct but reproductively compatible outcomes. Molecular signaling cascades in the developing gonad provide instructions to the tissue to develop as male or female (or in some cases hermaphrodite), and these signals can be initiated in different ways. Sex can be determined ...
متن کاملI-17: The Mechanism of Gonadal Sex Determination
Background In mammals, a single exon gene SRY on the Y-chromosome is activated in the XY gonadal primordium and initiates a cascade of molecular and morphological events leading to testicular differentiation. SRY-encoded protein (SRY) is a transcription factor harboring a HMG-box DNAbinding motif that upregulates SOX9, which encodes another transcription factor sharing the DNA binding motif wit...
متن کاملAn evidence of intersex males in Jajroud River Loach, Oxynoemacheilus bergianus (Derjavin, 1934)
In the present study, JajroudRiverloach, Oxynoemacheilus bergianus (Derjavin, 1934), was examined monthly for a previous observation of oocyte presence within testes tissues. Accordingly, the gonad development in O. bergianus is examined histologically. Although our data show typical fish gonad development and differentiation in female and some male individuals, some males sho...
