Nuclear staining of enadenotucirev in samples from selected CRC patients (IT injection versus IV infusion). 1. Image IT-204-B9-12 (top left), tumor section from a patient with CRC treated with enadenotucirev given by IT injection (cohort A): strong brown nuclear hexon staining of tumor cells is visible in the bottom part of the tissue section. 2. Image IT-204-B9-12 (top right), a different region of the same tumor section in 1: nuclear hexon staining of tumor cells is visible throughout this area of the tissue section. 3. Image IV-201-B10-9 (middle left), tumor section from a patient with CRC treated with enadenotucirev given by IV infusion (cohort B) but whose resection was delayed until day 52: nuclear hexon staining of tumor cells (but not stroma) is still visible in this tissue. 4. Image IV-101-B8-1 (middle right), non-tumor (presumed normal) section from a patient with CRC treated with enadenotucirev given by IV infusion (cohort B): little or no nuclear hexon staining is visible throughout the tissue section. 5. Image IV-302-B6-2 (bottom left), isotype staining control
