Developmental Biology of Teleost Fishes
On the contrary, as pointed out before, it is passively carried ahead by a pull
exerted from the independently expanding periblast. Ultrastructural analyses of
the margin have shown that in this region EVL and periblast are firmly attached to
...
The scene then changes; the marginal cells cease to produce central cells; when
their nuclei divide the peripheral daughter-nuclei move out into the periblast,
which is thus converted into a nucleated syncytium. The periblastic nuclei
multiply ...

Genetic Studies of Fish
Free peripheral periblast nuclei are not present. Stage 13. Late flat hollow
blastula. The enveloping layer cells undergo further flattening and an increase in
multinuclearity. Parallel alignment of adjacent cell surfaces characterize cell
junctions ...
blastoderm is called the marginal periblast. It is slightly darker in colour, and
remains continuous with the underlying yolk. As the development progresses,
cleavage begins in the periblast region also. The division of nuclei occurs rapidly
than ...
(A) Transverse section of early blastula showing adhesion of blastomeres to the
surface gel layer and attachment of blastoderm to the periblast at the periphery
only (Fundulus, after Trinkaus, 1951). (B) Sagittal section of later blastula
showing ...

This layer is called periblast. It consists of a large number of nuclei, lying
dispersed within a thin layer of cytoplasm. The cellular mass left above this layer
represents the blastoderm. [V] Blastula At the end of morula, a space called
blastocoel ...
Usually cleavage is not complete and in the deeper layers the periblast becomes
syncytial and is involved in mobilizing the yolk reserves. There are substantial
cohesive forces between the developing blastomeres and the surrounding ...

They stressed the close association of the PGCs with the syncytial periblast, an
observation which was confirmed by Hann (1927) and Wolf (1931). In Scardinius
