spindle fibremedical dictionary

<cell biology> Microtubules of the spindle that interdigitate at the equatorial plane with microtubules of the opposite polarity derived from the opposite pole microtubule organising centre. Usually distinguished from kinetochore fibres that are microtubules that link the poles with the kinetochore, although these could be included in a broader use of the term.
