Figure 6. Decreased FAM18B expression in CD34+/VEGFR2+ cells. Expression of FAM18B in CD34+/VEGFR2+ mononuclear cells from diabetic subjects with proliferative diabetic retinopathy is decreased compared to diabetic subjects without retinopathy. Glyceraldehyde 3-phosphate dehydrogenase (GAPDH) mRNA was used as internal standard for normalization. DM: diabetes without diabetic retinopathy (n=9). PDR: diabetes with proliferative diabetic retinopathy (n=8). *p-value <0.05.
