Furthermore, we observed that CXCL12AF647 was bound just via CXCR4 in the BL2, SuDHL4, and U2932 cells, whereas it was additionally bound via CXCR7 in the RI-1 cells, indicating that these two cell lymphoma lines also express CXCR7 on their surface (Figure S3b). This evidence concerns the gene CXCR4 and lymphoma.
