Gastrulation: Movements, Patterns and Molecules - Strona 67
positioning of its neuralizing and mesodermalizing parts), which may not be completed until late in gastrulation. These possibilities are hard to distinguish, especially if an aspect of the gastrula organizer's function is to complete its spatial ...

Principles of Development - Strona 167
The Wnt antagonist Frzb also generates a ventral-to-dorsal gradient of Wnt activity in the gastrula by binding to Wnt proteins and preventing them acting dorsally. Yet another signaling antagonist produced by the organizer is Cerberus, which ...

Patterning in Vertebrate Development - Strona 15
When cells from this region of an early Xenopus gastrula normally fated to form neural structures are transplanted to an ectopic position in another gastrula embryo, they do not develop into neural tissue but instead respond to signals in their ...

Principles of Developmental Genetics - Strona 911
analyses performed in the mouse, chick, and frog have mapped the movement of gastrulation-stage endoderm cells to broad domains of the developing gut tube and early organ primordia (Chalmers and Slack, 2000; Kimura et al., 2006; ...

Evolutionary Developmental Biology - Strona 228
Haeckel identified the gastrula as a universal metazoan stage equivalent to the metazoan ancestor, the Gastrea, although as Anderson and Richardson remind us, Haeckel was less than rigorous in his interpretation when depicting conserved ...

Developmental Biology - Strona 191
The transformation of a single walled blastula into a double walled gastrula is called gastrulation. Now the gastrula exhibits elongation in an antero-posterior direction. The wide mouth of the archenteron gradually narrows into a tiangular hole ...

Gene Activity in Early Development - Strona 167
genes operative in the embryo, since as reviewed above, the polysomes of the gastrula stage embryo include in toto about 8500 different message species. The criterion imposed by the highly sensitive hybridization methods utilized in these ...

Current Topics in Developmental Biology - Strona 64
Recent findings on morphology and gene expression in several mammalian embryos suggest that there is a new landmark and possibly a center with organizer activity in the anterior margin of the embryo at the onset of gastrulation.

1999

Invertebrate Oogenesis - Tom 1 - Strona 64
Meredith C. Gould. While the direct comparison of the relative template titers of egg and embryonic RNA tentatively suggests a slight decline in activity through blastulation, followed by a rise at gastrulation, the absolute numerical values upon ...
