Spindle assembly defects leading to the formation of a monopolar mitotic apparatus [PDF]
Mitotic spindle formation in animal cells involves microtubule nucleation from two centrosomes that are positioned at opposite sides of the nucleus. Microtubules are captured by the kinetochores and stabilized. In addition, microtubules can be nucleated independently of the centrosome and stabilized by a gradient of Ran—GTP, surrounding the mitotic ...

A Balance between Nuclear and Cytoplasmic Volumes Controls Spindle Length. [PDF]
Proper assembly of the spindle apparatus is crucially important for faithful chromosome segregation during anaphase. Thanks to the effort over the last decades, we have very detailed information about many events leading to spindle assembly and ...

USP11 deubiquitinates RAE1 and plays a key role in bipolar spindle formation. [PDF]
Correct segregation of the mitotic chromosomes into daughter cells is a highly regulated process critical to safeguard genome stability. During M phase the spindle assembly checkpoint (SAC) ensures that all kinetochores are correctly attached before its ...

Ontogenetic Alteration of the Spindle Apparatus: Possible Relation to Chromosome Pairing
SUMMARYAs the monocot Ornithogalum virens matures from seed germination to flowering there is a progressive reduction in the diameter of mitotic spindle apparatuses at the metaphase plate, and poles become more distinct. Apparently one result of this constriction of the spindle is a closer association of chromosomes on the metaphase plate which could ...

The association between muscle architecture and muscle spindle abundance
Across the human body, skeletal muscles have a broad range of biomechanical roles that employ complex proprioceptive control strategies to successfully execute a desired movement.

A spindle-like apparatus guides bacterial chromosome segregation [PDF]
Until recently, a dedicated mitotic apparatus that segregates newly replicated chromosomes into daughter cells was believed to be unique to eukaryotic cells. Here we demonstrate that the bacterium Caulobacter crescentus segregates its chromosome using a partitioning (Par) apparatus that has surprising similarities to eukaryotic spindles.

Mechanisms of spindle bipolarity establishment in acentrosomal human cells
Centrosomes are not absolutely essential for cell division; acentrosomal bipolar spindles can be established in oocytes and centrosome-eliminated somatic cells.
