Neutrophil Chemotaxis

Human neutrophils are mobile cells that will quickly migrate to sites of injury to help fight infection. They are attracted there by chemical signals released by other cells of the immune system or by invading microbes.

In this experiment substance is released from micropipette that makes the neutrophils polarize and move towards that location.
