1
Principles of Development
A graft of the organizer region, from the dorsal lip of the blastopore of an early
frog gastrula to the ventral side of another early gastrula, results in the
development of an additional anterior axis at the site of the graft (left panels). A
graft from the ...

Biology Coloring Workbook
At the completion of gastrula- tion, the embryo is called a gastrula. The
rearrangements of cells during gastrulation results in three primordial germ
layers called the ectoderm, mesoderm, and endoderm. These three germ layers
will later form ...

CURRENT TOPICS DEVELOPMENTAL BIOLOGY
Cytoplasniically induced changes in the morphology and synthetic activity of
transplanted early gastrula nuclei. (A) Typically lobed nuclei of early gastrula
cells. (B and C) Gastrula nuclei 1-3 hours after injection into oocytes or eggs.
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
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 ...

Color Atlas of Embryology
The primordial gastrula-type animal can be envisaged as functioning like a
suction cup that creeps along the ground and grazes on a bacterial lawn. The
structural principle of the gastrula is exemplified by the coelenterates. which
consist of an ...
A comparison of the kinetics of unfertilized egg and gastrula RNA mediated
amino acid incorporation The kinetics of concomitantly assayed unfertilized egg
and gastrula RNA directed [14C]serine incorporation are presented in Fig. 2.

degenerate at the time of gastrulation, and the degeneration is most evident in
that part of the gastrula in which the differentiation of the primary tissue layers is
taking place. This has been shown for Triton cristatus X T. palmatus by Pariser ...
