Growth

Polymerization and nucleation are the two microscopic processes in with the growth of asters occur. At the negative ends of the aster, centrosomes will nucleate (form a nucleus) and anchor to the microtubules. At the positive end, polymerization of the aster will occur towards the outer. Cortical Dyenein, a motor protein walks along the microtubules of the cell and plays a key role in the growth and inhibition of aster microtubules. Dyenein that is barrier-attached can inhibit and trigger growth.
