FIG. 5.
The expression of the homing receptor CXCR4 is downregulated in CFU-Hill cells from NPDR patients. The relative expression of CXCR4 and CXCR2 were measured by quantitative real-time PCR in the colonies formed by CFU-Hill cells of control subjects (n = 6), NPDR patients (n = 6), and patients with ≥23 years of diabetes and no retinopathy (n = 3). *P < 0.03 vs. the other two groups.
