Spindle fibers are formed from microtubules with many accessory proteins which help guide the process of genetic division. The spindle fibers form out of the centrosome, also known as the microtubule-organizing center, or MTOC. Septin hetero-oligomers polymerize into non-polar filaments, which in turn pair up to form higher order structures that serve as protein scaffolds and diffusion barriers. SURVEY .
