The dynamic lengthening and shortening of spindle microtubules, through a process known as dynamic instability determines to a large extent the shape of the mitotic spindle and promotes the proper alignment of chromosomes at the spindle midzone. Microtubule-associated proteins (MAPs) associate with microtubules at the midzone and the spindle ...
Spindle oils are a type of low-viscosity mineral oil marketed for use in lubrication of high-speed machine spindles. [1] Spindle oil is free from gumming properties. [2] Since the viscosity is so low that the oil runs off the surface of the spindle during shut-down periods, the spindle oil may be doped with additives that prevent rusting.
Cellulose fiber response to mechanical stresses change depending on fiber type and chemical structure present. Information about main mechanical properties are shown in the chart below and can be compared to properties of commonly used fibers such glass fiber , aramid fiber , and carbon fiber .
The spindle pole body (SPB) is the microtubule organizing center in yeast cells, functionally equivalent to the centrosome. Unlike the centrosome the SPB does not contain centrioles. The SPB organises the microtubule cytoskeleton which plays many roles in the cell. It is important for organising the spindle and thus in cell division.
Microtubule polymerization is nucleated at the microtubule organizing center. An aster is a cellular structure shaped like a star , consisting of a centrosome and its associated microtubules during the early stages of mitosis in an animal cell.
The microtubule-organizing center (MTOC) is a structure found in eukaryotic cells from which microtubules emerge. MTOCs have two main functions: the organization of eukaryotic flagella and cilia and the organization of the mitotic and meiotic spindle apparatus , which separate the chromosomes during cell division .
Different properties of MCC are measured to qualify its suitability to such utilization, namely particle size, density, compressibility index, angle of repose, powder porosity, hydration swelling capacity, moisture sorption capacity, moisture content, crystallinity index, crystallite size, and mechanical properties such as hardness and tensile ...
TPX2 has been shown in several biochemical assays to behave as a microtubule-associated protein (MAP) and co-localize with spindle microtubules during M-phase. [5] [17] [18] [9] [19] It plays a role in microtubule nucleation and is regulated by importin proteins.
