Wnt Signaling in Development
Expression of AmphiWnt-8 is first detectable at the onset of gastrulation
beginning at the same time and in the same pattern as brachyury — in a ring
around the equator of the late blastula corresponding to the future blastoporal lip
(Fig. 3A).

Xenopus laevis: Practical Uses in Cell and Molecular Biology
We distinguish a stage 10+, when a groove has formed and the blastoporal
pigment line is wider and beginning to curve ventrally. At 10.25 this line has
extended to 90° from the dorsal midline, and at 10.5 it has reached the ventral
midline.

Introduction to Marine Genomics
This is not the case in bilaterians, where the early apical- blastoporal (AB) axis is
not directly comparable to the bilaterian antero-posterior (AP) or dorso-ventral (
DV) axes. The single bilaterian AB axis often transforms into the AP and DV axis

is difficult to see, and its exact position is approximate (Fig. 6e, fine dashed line).
On the ventral side, the inner surface of the marginal zone where it bounds the
sub-blastoporal endoderm has the same characteristics (Fig. 6e, heavy dashed ...

Animal Evolution: Interrelationships of the Living Phyla
The first cleavage begins at the blastoporal pole, and the cleavage furrow cuts
towards the apical pole, so that a peculiar stage with the two blastomeres
connected by an apical 'handle' is formed before the blastomeres finally separate
; similar ...

2 The Hydra Head Organiser Is an Organiser Equivalent to the Blastoporal
Organiser in Bilaterians A source of Wnt ligands in many metazoan embryos is
the blastoporal signalling centre. In cnidarians the blastoporal region of most
embryos ...

The Algorithmic Beauty of Sea Shells
These blastoporal rings, small in hydra and huge in amphibians, are the source
region of a signaling substance, Wnt, that controls anteroposterior determination
in a gradient-based manner (fading blue, see also Figure 12.9). The cells of the ...

Advances in Morphogenesis
During furtherdevelopment theembryos formeither oneor more blastoporal lips at
sites markedly removed fromthe original graycrescent area. However, the
blastoporal lips are always formed at the boundary ofthe yolk mass and bear
acertain ...

Its central portion thins out into a single cell layer - the so-called area pellucida,
below which a subgerminal cavity is formed - while the periphery of the disc
thickens, particularly on its future posterior side, forming the so-called blastoporal
or ...

Form and Causality in Early Development
Gastrulae may be cut along the median sagittal plane, or in its immediate
neighbourhood, and their halves are able to form dwarf embryos with almost
perfectly symmetrical organs.2 Lateral halves of the young blastoporal lip, when
grafted in ...
