Figure 5.

Liver sections from SCID mice injected intravenously or intratumorally with the adenoviral vectors. The i.v. experiment was described previously (see Fig. 5 in ref. 11), and the intratumoral experiment is described in Fig. 4. The panels on the left were injected with the control vector, and the panels on the right were injected with a mixture of the two vectors encoding the mfVIIasm and G71-1 immunoconjugates. The livers were dissected 2 days after the last injection, were fixed in formaldehyde, and were embedded in paraffin. The sections were stained with hematoxylin and eosin and were photographed at a magnification of 100×.
