(A) Vector copy number (VCN) indicating the distribution of integrated LV genome along the rostro-caudal axis (slices 7-19) in LV.hGALC-injected NHPs (JT02 and JV02) assessed by qPCR. Each dot represent the VCN measured in one block within the slice. Lower threshold (dotted line): VCN<0.001, corresponding to CT>37.
