FIG. 1. — The number of circulating CD45^dim EPCs is similar in type 1 diabetic patients with NPDR (n = 20) or without NPDR after short (≤7 years, n = 19) or long (≥23 years, n = 17) diabetes duration and age- and sex-matched control subjects. The cells were enumerated by flow cytometry using a hierarchical gating strategy to count only CD34⁺VEGFR-2⁺ cells negative for the pan-hematopoietic cell marker CD45 or expressing only low levels (CD45^dim). Each box plot shows the 10th, 25th, 50th (median), 75th, and 90th percentiles of the counts obtained in the respective group. Values >90th and <10th percentile are plotted as individual points.
