ABSTRACT
<p><b>OBJECTIVE</b>To investigate the effect of stromal cell derived factor-1alpha(SDF-1alpha) expression and its receptor CXCR4 on the biological behavior of multiple myeloma (MM) cells and on the expression of soluble intercellular adhesion molecule 1 (ICAM-1).</p><p><b>METHODS</b>FACS analysis was used to study the expression of ICAM-1 (CD(54)) and CXCR4 on the surface of MM cells. Chemotaxis assay through transwell bore polycaronate and ELISA assay were employed to monitor the soluble ICAM-1 level.</p><p><b>RESULTS</b>(1) Fresh MM cells expressed variable levels of functional CXCR4 [(50.4 +/- 27.3)%], which was correlated with the in vitro ability of transwell migration of MM cells [(23.6 +/- 17.2)%, P < 0.01]. (2) SDF-1alpha could up-regulate the expression of ICAM-1 on MM cells. Furthermore, the serum level of sICAM-1 was correlated with the expression of CXCR4 on MM cells.</p><p><b>CONCLUSION</b>SDF-1alpha/CXCR4 plays an important role on the biological behavior of MM cells via mediating the effect of adhesion molecules.</p>
