Ex vivo assessment of human neutrophil motility and migration.

Neutrophils are pivotal in orchestrating tumor-induced systemic inflammation and are increasingly recognized for their critical involvement in both the initiation and progression of cancer. A fundamental facet of neutrophil biology is their migratory capacity, which enables them to extravasate and infiltrate tumors in other tissues, where they carry out essential effector functions. Unraveling the intricate mechanisms of neutrophil motility and migration is crucial for comprehending immune responses and inflammatory processes, shedding light on their substantial contribution to cancer progression. Here, we provide a comprehensive protocol to assess direct ex vivo motility and migration of freshly isolated human neutrophils, offering valuable insights into their behavior.
