OSA derives from primitive bone-forming mesenchyme and it is characterized by the proliferating spindle cells production of osteoid tissue or immature bone.
The capture of chromosomes at both sister kinetochores, by microtubules of the mitotic spindle, silences the production of this signal.
► Spindle orientation influences neuron production and cortical size by regulating production of intermediate progenitors and outer radial glial progenitors.
In this model, the machining spindle speed — which affects production time, power and noise — is flexible and is treated as an independent decision-making variable.
This paper describes the design and evaluation of two contact probes used to measure the length and bore concentricity of cylindrical, extruded tool joints while clamped in a production lathe spindle.
It is presently unclear which mechanism is responsible for slowing down MT production during spindle assembly.
What is the implication of autocatalytic MT production for spindle assembly?
Griseofulvin (a tricyclic spirodiketone, first isolated from Penicillium griseofulvum) acts by disrupting spindle and cytoplasmic microtubule production, thereby inhibiting fungal mitosis.
They concluded that different transcript levels in normal and aneuploid oocytes may have an impact on cellular pathways, such as meiotic spindle assembly, chromosome alignment, production of cell surface or excretory molecules, and might potentially serve as targets for noninvasive oocyte aneuploidy assessment.
While centrosomes are considered to be the main source of MT production in mitotic spindle assembly, the mechanism of MT production during assembly of anastral spindles, which do not have centrosomes, is unknown.
Cytokines produced by inflammatory cells induce normal endothelial cells to acquire the features of KS spindle cells and to induce production of angiogenic factors [5].
