Relationship of Human Neutrophil Morphology and Actin Distribution to Dispersive Locomotion caused lbumin-coated glass surface. In this paper we show that this factor inhibits adhesion of neutrophils to bovine aorta and human endothelial cells by an undetermined mechanism. It induces unique changes in neutrophil shape with a characteristic monopolar pattern of F-actin distribution, which may corr作者: 生氣的邊緣 時(shí)間: 2025-3-24 15:43 作者: 松軟無(wú)力 時(shí)間: 2025-3-24 20:10 作者: Nuance 時(shí)間: 2025-3-25 02:48
