Actin mixes up mitochondria for inheritance

In cells that divide symmetrically, a meshwork of actin cables is shown to maintain the uniform distribution of mitochondria around the mitotic spindle. Actin clouds and comet tails are assembled dynamically to shuffle mitochondria locally and ensure the equal and random inheritance of these organelles by the two daughter cells. Actin clouds and comet tails ensure the uniform distribution of mitochondria during mitosis.
