Crawling-like movements of polymorphonuclear leukocytes in plasma are not a good index of their motility in microporous cellulose acetate membrane.
Crawling-like movements, motility and adhesiveness of polymorphonuclear leukocytes (PMN) in various concentrations of autologous plasma were assessed using microporous cellulose acetate membranes. In 0% plasma, crawling-like movements and motility were low, while adhesiveness was high. In 10% plasma, crawling-like movements remained low, motility was high and adhesiveness fell to a minimum. In 30%, 60% and 100% plasma, crawling-like movements progressively increased, motility rose (at 30%) and then fell slightly (at 100%) while adhesiveness did not change. The results indicate that crawling-like movements of PMN suspended in plasma are not a good indicator of the motility of these cells in cellulose acetate membrane.
