It appeared that OV-αCD47-G1-infected U251T2 GBM cells produced a slightly higher level of anti-CD47 antibody than OV-αCD47-G1-HL-infected GBM cells (Supplementary Fig. 2b), and thereafter all subsequent experiments were performed using OV-αCD47-G1 instead of OV-αCD47-G1-HL. The gene discussed is CD47; the disease is glioblastoma.
