A little guide for advanced search:

  • Tip 1. You can use quotes "" to search for an exact expression.
    Example: "cell division"
  • Tip 2. You can use + symbol to restrict results containing all words.
    Example: +cell +stem
  • Tip 3. You can use + and - symbols to force inclusion or exclusion of specific words.
    Example: +cell -stem
e.g. searching for members in projects tagged cancer

The assembly of a mitotic spindle requires the interaction of microtubules with chromosomes. As a cell enters mitosis, long microtubules are converted to short ones, as microtubules become unstable. Dynamic microtubules are then stabilised by chromosomes, forming a bipolar spindle. In this review, we discuss the different roles of kinetochores and chromosome arms during spindle assembly. Kinetochores, required for proper chromosomes segregation, capture microtubules and maintain attachment. Chromosome arms greatly enhance microtubule stability, and alone can be sufficient for spindle assembly.
