Chitin and Chitosan Induce Migration of Bovine Polymorphonuclear Cells

Bovine polymorphonuclear cells (PMNs) were found to migrate to suspensions of finely granulated chitin and chitosan of an average size of 1 μm at higher rates than to those of an average size of 30 and 50 μm, respectively, through a 5 μm pore size polycarbonate filter in a Blind well chamber.
