Circulating Endothelial Progenitor Cells in Kidney Transplant Patients
Figure 3
Circulating levels of endothelial progenitor cells (EPC) in renal transplant recipients.
EPC levels were directly quantified from whole blood taken from control subjects and patients (RTx) by flow cytometry, which identifies EPCs according to the expression of cell surface antigens, such as (A) CD133+ and VEGF-R2+; and (B) CD34+ and VEGF-R2+. P value compared to control group is indicated (Mann-Whitney test).
