The
early interphase 10 reconstruction is of a 42 micron wide by 28 micron
high by 20 micron deep volume
of the syncytial blastoderm
of a Drosophila embryo fixed in early interphase 10, just as the migrating
nuclei
first approach the cortex.
In the first-displayed frames the cortex is closest to you. Centrosomes
are
white or magenta. Microtubules
are yellow. Chromatin is greenish. Yolk particles are gray.
F-actin is orange.
Note the caps of concentrated
F-actin overlying the centrosomes. When the reconstruction rotates 180
degrees,
so you are looking toward
the cortex from inside the egg, you can see the tunnels through the yolk
particles
the nuclei made as they
migrated. The remnants of the mitotic spindles from the previous
round of mitosis
remain well into interphase.
