Patterning the early Xenopus embryo.
Developmental biology teachers use the example of the frog embryo to introduce young scientists to the wonders of vertebrate development, and to pose the crucial question, 'How does a ball of cells become an exquisitely patterned embryo?'. Classical embryologists also recognized the power of the amphibian model and used extirpation and explant studies to explore early embryo polarity and to def...
متن کاملThe role of Mixer in patterning the early Xenopus embryo.
The transcription factor VegT, is required in early Xenopus embryos for the formation of both the mesoderm and endoderm germ layers. Inherited as a maternal mRNA localized only in vegetal cells, VegT activates the transcription of a large number of transcription factors, as well as signaling ligands that induce cells in the vegetal mass to form endoderm, and the marginal zone to form mesoderm. ...
متن کاملNew roles for FoxH1 in patterning the early embryo.
FoxH1 (Fast1) was first characterized as the transcriptional partner for Smad proteins. Together with Smad2/4, it forms the activin response factor (ARF) that binds to the Mix.2 promoter in Xenopus embryos. Foxh1 is expressed maternally in Xenopus. Depletion of maternal Foxh1 mRNA results in abnormalities of head and dorsal axis formation. We show that FoxH1 is required, together with XTcf3/bet...
متن کاملGenetic dissection of nodal function in patterning the mouse embryo.
Loss-of-function analysis has shown that the transforming growth factor-like signaling molecule nodal is essential for mouse mesoderm development. However, definitive proof of nodal function in other developmental processes in the mouse embryo has been lacking because the null mutation blocks gastrulation. We describe the generation and analysis of a hypomorphic nodal allele. Mouse embryos hete...
متن کاملThe Molecular Harbingers of Early Mammalian Embryo Patterning
Random or not, the mechanisms at play during the first cell-fate determination in mammalian embryos have been debated for years. Studies by Goolam et al. and White et al. shed new light on the molecular mechanisms underlying the intrinsic biases that lead to non-random lineage segregation in early mammalian development.
