Spindle apparatus - Wikipedia
In a properly formed mitotic spindle, bi-oriented chromosomes are aligned along the equator of the cell with spindle microtubules oriented roughly perpendicular to the chromosomes, their plus-ends embedded in kinetochores and their minus-ends anchored at the cell poles.
Spindle Fibers: Definition, Structure, & Functions, with Diagram
2023年2月17日 · Spindle fibers are a network of filaments called microtubules that move chromosomes during eukaryotic cell division. Spindle fibers formed in mitosis are called the mitotic spindle, while those formed in meiosis are called the meiotic spindle. Microtubules that form the spindle fibers come from centrosomes. Spindle fibers play a significant ...
Spindle Fibers - The Definitive Guide - Biology Dictionary
2020年11月18日 · Spindle fibers are microscopic protein structures that help divide genetic material during cell division and organize cellular components. The spindle fibers form out of the centrosome, also known as the microtubule-organizing center, or MTOC.
Mitotic spindle: kinetochore fibers hold on tight to interpolar …
These interpolar bundles, termed bridging fibers, balance the forces acting at kinetochores and support the rounded shape of the spindle during metaphase. This review discusses the structure, function, and formation of kinetochore fibers and interpolar …
Mitosis - Molecular Biology of the Cell - NCBI Bookshelf
Three classes of spindle microtubules can be distinguished in mitotic animal cells (Figure 18-10). Astral microtubules radiate in all directions from the centrosomes and are thought to contribute to the forces that separate the poles.
Mechanisms of Mitotic Spindle Assembly - PMC - PubMed …
Upon describing the basic spindle anatomy and defining its constituents, we first discuss bulk and single-molecule methods that have allowed inference of the dynamic behavior and organizations of MTs within the metaphase spindle and the principles …

During mitosis, the spindle fibers are called the mitotic spindle. Meanwhile, during meiosis, the spindle fibers are referred to as the meiotic spindle.
Mechanisms and Molecules of the Mitotic Spindle - Cell Press
2004年9月21日 · Here we describe current models and discuss some of the complex repertoire of factors required for spindle assembly and chromosome segregation. Essential to the process of cell division is the mitotic spindle, which partitions a …
Cell Division Dynamics: Key Components and Processes
6 天之前 · Spindle Dynamics. The spindle apparatus is an intricate and dynamic structure that ensures the faithful distribution of genetic material during cell division. Its formation marks a transformation within the cell, where a complex network of fibers emerges to guide chromosomes to their respective destinations.
Here we describe current models and discuss some of the complex repertoire of factors required for spindle assembly and chromosome segregation. Essential to the process of cell division is the mitotic spindle, which partitions a complete set of chromo-somes to each daughter cell.
