摘要：

Cell-cell adhesion is probably the hest cell function to be considered for biophysical modeling from micrometer to the molecular level. The aim of this study is to find a relation between the bulk properties of erythrocytes suspension (like surface tension and viscosity) and erythrocytes adhesion. Our results showed that there is a strong correlation between surface tension and adhesion number (r(2) = 0.85) and moderate correlation between erythrocytes suspension viscosity and adhesion number (r(2) = 0.55). Our results were indicated that bulk properties of erythrocyte can affect directly oil microscopic properties of erythrocytes. (C) 2008 Elsevier B.V. All rights reserved.
