Differential Fy epitope exposure on SDF-1-interacting reticulocytes. (a) Schematic representation of DARC membrane protein, including Fy^A, Fy^B, Fy³, Fy⁶ epitopes. (b) Mean fluorescence intensity (MFI) of DARC epitope Fy⁶ Fy^a, Fy^b, Fy³ and Glycophorin-A, an erythroid specific marker, used as a control (CD235a), on erythrocytes (RBC), reticulocytes (retic.) and SDF-1 positive reticulocytes (SDF-1 + Retic.), presented in fold change and normalized to erythrocytes. (Paired T-test, n = 4–5, ns: not significant; *P < 0.05; **P < 0.01; ***P < 0.001).
