Where they intersect the Washington Monument rises into the sky, the great spindle around which the garden turns.
To induce formation of a single spindle around both DNA beads and sperm chromatin, DNA beads and sperm chromatin were co-injected into eggs.
A RanGTP gradient has been proposed to provide the spatial cues necessary to position the spindle around chromatin (reviewed in [7], [8], [12]).
Guide wheels and steady wheels are connected to the end support arms of the framework through spindles around the horizontal direction.
When vibrations are applied, for example, to the muscle spindles around the elbow, and the eyes of the subject are closed, it is possible to induce the illusion that the forearm is opening (or closing - depending on exactly where the vibration is applied) [14].
39 The authors proposed that the distribution of muscle spindles around each joint could explain differences in perception of position sense and commented on the relative importance of proximal joints in localizing the endpoint.
Occasionally, cells had three or four spindles, with each spindle formed around chromosomes or bivalents (data not shown).
During oogenesis, MAPs are believed to stabilize microtubules preferentially close to condensed chromosomes, favoring spindle assembly around DNA.
To test this possibility further, we injected sperm chromatin into MII eggs and cultured the eggs for 2 3 h to allow spindle formation around the sperm chromatin (Figure 3A).
The ET shows that the spindle contains around thirty microtubules during metaphase, and that this number is reduced dramatically by kinetochore-fibre depolymerisation in anaphase A. Upon entry into anaphase B, the spindle is constructed from only ten microtubules, which are then lost progressively from the spindle until only six remain prior to its disassembly.
In case 1, the inner atypical ductal cells in the transitional area were positive for GCDFP-15, AR, Her-2, pan-CK, and EMA, whereas the spindle cells around such ductal cells were positive for ASMA, calponin, CK14, p63, and S-100 protein; therefore, this lesion was considered as an in situ component of salivary duct carcinoma.
