... present evidence that Wnt signaling also patterns the proximal-distal nephron axis. Using the chick mesonephros as a model system, a Wnt ligand was ectopically expressed in the coelomic lining, thereby introducing a source of Wnt signaling that is at right angles to the endogenous Wnt signal...

... of the mesonephric mesenchyme into tubular and glomerular segments. The results are discussed in terms of their broader implications for models of nephron segmentation. In addition to the typical nephrons of the mesonephros and metanephros, avian embryos have long been known to form structures in the pronephric...

...David Grote; Abdallah Souabni; Meinrad Busslinger; Maxime Bouchard The mammalian pro- and mesonephros are transient embryonic kidneys essential for urogenital system development. The nephric (Wolffian) duct,which is a central constituent of both structures, elongates caudally along a stereotypical...

...Christopher Tilmann; Blanche Capel ABSTRACT In mammals a single gene on the Y chromosome, Sry , controls testis formation. One of the earliest effects of Sry expression is the induction of somatic cell migration from the mesonephros into the XY gonad. Here we show that mesonephric cells...

...Mia Buehr; Subin Gu; Anne McLaren ABSTRACT Testes from 11.5-day-old mouse embryos, with and without attached mesonephroi, were cultured for 7 days. Isolated testes failed to develop well-differentiated testis cords: however, when cultured attached to a mesonephros from either a male or a female...

... regions. Ghox 2.2 RNA is found in trunks and limb buds, but it is strikingly absent from the developing head. In situ hybridization with 35 S-labelled antisense riboprobes derived from Ghox 2.1 demonstrates that this gene is expressed at high levels in spinal chord, myelencephalon and mesonephros. Dorsal...

... chimaeras were produced by transplantation of corresponding quail tissue in the region of somites 18–21. A morphometrical analysis of the mesonephric and gonadal area in cross sections shows that the intermediate mesoderm from somites 16 to 23 develops into the mesonephros. A partial agenesis...
