Gene Activity in Early Development
In normal embryos the 3D macromere is usually, but not necessarily, one of the
two “vegetal cross furrow” macromeres shown in Fig. 6.20 (a). The event that
specifies which will become the D macromere, and hence that determines the ...

7.1A, stage 2). Second cleavage is meridional as well, with blastomere CD
dividing unequally to produce a larger D macromere (which receives the
teloplasm) and a smaller C macromere. The ensuing equal cleavage of
blastomere AB results ...
second cleavage the embryo can be said to consist of two C and two D
macromeres, where D is the macromere into which the lobe is subsequently
resorbed, and C is its sister macromere. There are no A or B type macromeres.

Clement ('62) has shown, through his D quadrant macromere deletion studies,
that external shell develops only after 2d is formed. Even though all of the
ectoderm used in the formation of the shell is present at this time, the shell is
never ...

To test this possibility, HRP was injected into an A, B, or C macromere of Stage 3
embryos, i.e., prior to micromere formation. (Because of the small size of the
micromeres, the preferable procedure of directly injecting them in Stage 4a ...

Phylogeny and Evolution of the Mollusca
Deletions of the D macromere were performed in the gastropod Ilyanassa and
the scaphopod Antalis (as Dentalium) with similar results (Clement 1962; Cather
and Verdonk 1979). In these experiments, deletion of the polar lobe or the D ...

Eventually each macromere divides more equally to give two macromeres, one
behind the other. At this stage, the 34-cell stage, each macromere has given rise
to two generations of micromeres posteriorly and, then, one generation anteriorly.

As described above, the ricin-injected macromere rounds up, and consequently
becomes partially enveloped by the other macromeres, but does not lyse. The
remaining cells in the embryo seem unaffected; for example, the rate at which ...

Van den Biggelaar (1976) has recently put forward the hypothesis that
dorsalisation of the Limnaea egg is purely a question of the attainment of an
equilibrium position by the macromeres, one of them, then called the D
macromere, achieving ...

The posterior macromere in Clepsine, as we have seen. is the sole source Oi the
germ-hands, and its history is the key to subsequent develome Unfortunately our
knowledge of this macromere in Nephel'ts is not complele enough to warrant ...
