Abstract:
AIM and METHODS: To investigate the expression of adhesion molecule ? 2 integrins (CD11a、CD11b) and L-selectin(CD62L )on Acute Lymophocyte Leukemia(ALL) cells and its Clinical Implications. Adhesion molecules CD11a、CD11b、 CD62L of 45 ALL patients and 25 health people were measured by flow-cytometric analysis. RESULTS:①CD11a and CD11b expression were lower on ALL cells than the normal hematopoietic cells. The rate of low expression was 100% for CD11b, 50% for CD11a,respectively. CD62L expression were higher on ALL cells than the normal hematopoietic cells.②The CD11a was lower expressed on B-ALL than T-ALL. CD62L was higher on T-ALL than B-ALL. ③ The expression of CD11a in the invasion group was much higher than that in the non-invasive group(P
