abstract：:To study the role of SDF-1/CXCR4 axis in MDS, the expression of SDF-1 and CXCR4, VEGF, MVD and apoptosis were measured in MDS. The results showed that the expression of SDF-1 of the low-grade MDS is higher than that of the high-grade MDS and the control. The high-grade MDS had a significantly higher CXCR4 expression o...
