چکیده

Intercellular adhesion is measured by a new method based on determination of the rates of attachment of single cells to confluent cell monolayers. The procedure is simple, rapid, and reproducible. Specific and nonspecific intercellular adhesions can be quantitated and distinguished from each other, and from the adhesion to glass (or plastic). The rate of adhesion of single cells to the monolayer is characteristic of more than 80% of the single-cell population. This method, therefore, provides a means for study of the molecular basis of intercellular adhesion.

Intercellular adhesion as a function of the cell cycle traverse

Intercellular adhesion is assumed to play an important role in a multitude of biological phenomena governing cellular behavior. The rate of intercellular adhesion as a function of the cell cycle traverse has been investigated using, in the monolayer assay, synchronized Chinese Hamster Ovary-K1 cells. Results obtained demonstrate that cells in G1 adhere to G1 cells at twice the rate that S cells...

Intercellular adhesive selectivity. III. Species selectivity of embryonic liver intercellular adhesion

A species difference in the intercellular adhesive selectivity of mixtures of embryonic liver cells is reported. This is first quantitative assessment of species differences in the intercellular adhesive properties of embryonic cells. A collecting aggregate assay, a new double-label assay procedure, and histological and autoradiographic procedures were used to elucidate the intercellular adhesi...

Pentoxifylline Decreases Serum Level of Adhesion Molecules in Atherosclerosis Patients

Background: Inflammation is involved in development, progression, and complications of atherosclerotic disease. Clinical studies have indicated that the level of monocyte chemoattractant protein 1 (MCP-1), IL-18, and adhesion molecules correlates with the severity of atherosclerosis and can predict future cardiovascular events. Experimental studies have shown pentoxifylline (PTX) reduces these ...

Effect of one Bout Continuous Versus Intermittent Aerobic Exercise on Plasma Levels of Intercellular Adhesion Molecules 1 and Vascular Cell Adhesion Molecules 1 in Patients with Coronary Heart Disease

Introduction: Adhesion molecules play an important role in the pathogenesis of atherosclerosis and the type of training may affect the response to these indicators. Therefore, the purpose of the present study was to investigate the effect of a continuous versus interval aerobic training session on plasma levels of intercellular adhesion molecules 1 (ICAM-1) and vascular cell adhesion molecules ...
