SU-positive cells in JSRV-infected lung slices are CCSP negative and DC-LAMP positive. Serial sections of A-C) OPA-N; D-F) JSRV-infected lung slice,16 dpi and G-L) JSRV-∆RT-infected lung slice 16 dpi were subjected to IHC for JSRV SU and for respiratory epithelial cell markers: A, D, G, J) anti-JSRV SU; B, E, H, K) anti-DC-LAMP; C, F, I, L) anti-CCSP; Figure 5A and G/J show positive and negative controls, respectively, for JSRV SU-labeling. Note areas of co-labeling with markers for OPA tumor cells and type II pneumocytes (A/B and D/E) but no co-labeling with the marker for club cells (C and F).
