[A study of leukocyte chemotaxis in a glass micropipette].

Chemotaxis, the directional locomotion of a cell toward a source of a chemical gradient, is an important phenomenon occurring for mobilizing immune cells at sites of infection and injury. This phenomenon has been simulated in analyzing the movement in vitro of a chemoattracted cell inside a glass micropipette. A microneedle filled with fMLP, N-formyl-methionyl-leucyl-phenylalanine, at a concentration of 9.
