Once neutrophils exit the bloodstream through transendothelial migration, they encounter several chemoattractants that help direct them toward the injured tissue. Once they have arrived at the site of inflammation, neutrophils perform several immune functions to eliminate pathogens and clear any possible debris.
An example of neutrophil swarming behavior by neutrophil extracellular traps. The neutrophil (green) surround branches of the Aspergillus Fumigatus (light blue) in infected lung tissue in a swarming manner and transport the branches to the neutrophil aggregates on the left. The dark blue color indicates lung tissue and the red color indicates DNA.
Neutrophils extravasate from blood vessels to the site of tissue injury or infection during the innate immune response.. In immunology, leukocyte extravasation (also commonly known as leukocyte adhesion cascade or diapedesis – the passage of cells through the intact vessel wall) is the movement of leukocytes (white blood cells) out of the circulatory system (extravasation) and towards the ...

Scratch wound healing assay experiment of rhabdomyosarcoma, a cancer cell line. A wound healing assay is a laboratory technique used to study cell migration and cell–cell interaction. This is also called a scratch assay because it is done by making a scratch on a cell monolayer and capturing images at regular intervals by time lapse microscope.
The mediator molecules also alter the blood vessels to permit the migration of leukocytes, mainly neutrophils and macrophages, to flow out of the blood vessels (extravasation) and into the tissue. The neutrophils migrate along a chemotactic gradient created by the local cells to reach the site of injury. [ 9 ]
