Study challenges five-decade paradigm of strict division of labor in animal cell division
By
William Bement
Summary
This article challenges the long-held view that animal cell division involves a strict division of labor, where microtubules handle chromosome transport and separation while actin filaments (F-actin) and myosin-2 handle cell splitting. This paradigm has persisted for over five decades, with any exceptions dismissed as special cases. The article presents evidence that this traditional view is being reconsidered, suggesting that actin filaments may also play a role in mitosis alongside microtubules.

Transporting, organizing, and then separating the chromosomes is the job of microtubules and microtubule-associated proteins that constitute the mitotic spindle, whereas splitting the cell itself is the job of actin filaments (F-actin) and myosin-2.
This view has persisted for more than five decades, with any exceptions considered as special cases.
