We performed the measurements of the chemo attractants, Monocyte chemoattractant protein-1(MCP-1) and Stromal cell-derived factor-1 (SDF-1), and growth factors, Vascular endothelial growth factor (VEGF) and Pigment epithelium-derived factor (PEDF), but found high variability in the expression level of these factors with no differences between control, diabetes and treatment groups (data not shown). The gene discussed is CXCL12; the disease is diabetes mellitus.
