The phrase "axis of the spindle" is correct and usable in written English.
It can be used in contexts related to machinery, engineering, or anatomy where the orientation or central line of a spindle is being discussed.
Example: "The technician adjusted the axis of the spindle to ensure proper alignment during the machining process."
Alternatives: "spindle axis" or "central axis of the spindle".
Only oocytes where the long axis of the spindle was in the x y plane were included such that centromere kinetochore separation could be measured accurately.
Spindles were analysed using Image J software, by creating a region of interest and using the 'plot profile' plugin to capture the tubulin and H2B intensity along the long axis of the spindle.
These divisions are mediated by meiotic spindles that are asymmetrically positioned against the oocyte cortex with the pole-to-pole axis of the spindle perpendicular to the cortex.
This unique morphology facilitates counting of individual chromosomes on the metaphase plate when viewed down the pole-to-pole axis of the spindle.
Spindles were therefore classified accordingly in these two, cell-biologically equivalent, perspective categories, a 'Front' view, when the main axis of the spindle was mostly parallel to the sectioning plane and fully visible within 1 3 confocal sections, and a 'Side' view, when the main axis of the spindle extended mostly along the sectioning axis.
The granularity of the isotropic fibre tracking analysis (IFTA) solution is controlled by a single parameter, Rs, which specifies the separation of neighbouring coordinates that define the axis of the spindle in three-dimensions.
When telophase chromatin is viewed in the axis of the mitotic spindle, the "core" refers the central region at surfaces both proximal and distal to the spindle.
In both of these situations, if the division axis that is defined by the axis of the mitotic spindle is coordinated parallel to the axis of cell polarity, the 2 daughters receive determinants or extracellular signals differentially, causing them to assume different fates.
This work proposed a model in which horizontal divisions where the axis of the mitotic spindle is parallel to the apical surface of the neuroepithelium are symmetric and proliferative, giving rise to 2 apical progenitors, whereas vertical or oblique divisions are asymmetric and neurogenic, generating a basal neuron and an apical progenitor (Fig. 1 B ).
Asymmetric cell divisions combine cell division with fate specification and one general model of how this is achieved was proposed already decades ago: During interphase, the cell polarity axis is specified, followed by orientation of the spindle along the polarity axis and segregation of fate determinants along the polarity axis during mitosis.
A fragile spindle was classified as a short bipolar spindle with lower intensity tubulin staining in the middle of the spindle axis.
