Stimulated human PMN.
(A) Enhanced transmitted light image of fMLP (10−7mol/L)-stimulated human PMN adhering to collagen. (B) Corresponding image in laser-emitted fluorescent light showing immunofluorescent staining for α2β1. Combined examination of cell morphology and α2β1 integrin expression revealed that the receptor was localized to the lamellipodium in the front of PMN having a distinct head-tail morphology (arrow). Bar indicates 5 μm.
