WebChemotaxis of rabbit mononuclear cells was studied by the micropore-filter technique. Mononuclear cells obtained from mineral oil-induced peritoneal exudates respond chemotactically to rabbit serum treated with immune complexes or with streptokinase and plasminogen, to soluble factors produced by bacteria, and to lysates obtained from rabbit …

WebFor chemotaxis to 10 nM FMLP, there was a significant group time interaction (F 3.7, p.03), showing an increase in chemotaxis to FMLP in response to the speech task (Figure 1). For chemotaxis to SDF-1 (Figure 2) there was a significant group time interaction (F 3.2, p.05), also revealing an increase in chemotaxis in response to stress. For WebChemotaxis assays analyze cell migration in response to a chemoattractant, a process that guides cell trafficking in vivo.

It is shown that under an appropriate hypothesis for p and δ, there exists a locally bounded global weak solution of the corresponding initial–boundary problem.
