Daughter cells may be deformed because I think the spindle fibers
help the cell keep its shape.
Consequently, non-disjunction of chromosome and chromosome abnormality were caused by spindle fiber
damage during the matured oocyte cryopreservation.
In subsequent studies, Inoue and collaborators established the reversible assembly and disassembly of spindle fibers and fibrils in living cells when exposed to cold temperatures (Inoue, 1964), antimitotic drugs (Inoue.
For example, the OI-DIC picture displays the chromosomes, while the LC-PolScope image shows the spindle fibers (Shribak et al.
gamma]-tubulin is clearly associated with the shorted spindle fibers
in the polar regions (Fig.
C) The chromosomes line up along the spindle fibers
Asters disappear as a tetrapolar spindle is assembled; microtubules emanating from the four poles are organized into spindle fibers
at the surface of the tetrahedral nucleus (Fig.
If all kinetochores are not attached to spindle fibers, then what would be observed in the cell?
Separase would be active before all kinetochores were attached to spindle fibers.
As a result, with each additional bounce, the tension and stretch of the muscle increases, stimulating the muscle spindle fibers
We now demonstrate, at these General Scientific Meetings, through-focal and three-dimensionally reconstructed stereoscopic images of a free-swimming, pluteus-stage sea urchin embryo and the mitotic spindle fibers within the two-cell stage of a dividing ctenophore egg.
The spindle of the dividing ctenophore egg, reconstructed from serial optical sections in polarization microscopy, shows the 3-D organization of the birefringent chromosomal spindle fibers (kinetochore microtubule bundles) in rocking stereoscopic projection.
