The shrinking end leaves a chemical trace behind having high local tubulin concentration. Similarly, the growing end grows in the regions with excess of tubulin. Produced by microtubules chemical traces activate and deactivate the formation of neighbouring microtubules
Microtubles produce spindle fibers during cell division microtubles are one of the organelles. Microtubules continually grow at one end and shrink at another.
microtubules
Microtubules are conveyer belts inside the cells. They move vesicles, granules, organelles like mitochondria, and chromosomes via special attachment proteins. They also serve a cytoskeletal role. Structurally, they are linear polymers of tubulin which is a globular protein.

This is cool. I am learning about this in Biology class right now.
