title: Leukocyte migration in different systems. Effect of colchicin. Kinetics of migration under agarose.
abstract: In a double-filter modification of Boyden's method, formylmethionylleucylphenylalanine (FMLP) needed the presence of fresh plasma to induce leukocyte locomotor kinetics which compared with a model for directional migration. FMLP, or zymosan-activated plasma, did not stimulate migration in capillary tubes. The kinetics of leukocyte migration under agarose towards zymosan-activated plasma were more compatible to a model for increased random motility than for directional migration. Treatment of leukocytes with colchicin reduced their migration under gradient and non-gradient conditions in millipore filters, capillary tubes, and in under-agarose experiments.
