to allow a further understanding of the pathogenesis of impaired stimulated locomotion by polymorphonuclear leukocytes ( pmns ) in human neonates , we studied cellular orientation by neonatal pmns in response to well-defined chemotactic gradients ( zigmond orientation chambers ) and characterized the cytoplasmic microtubule ( mt ) complex of neonatal pmns during cell orientation and movement .
