Treatment of human xenograft tumors in nude mice with RCNV. Human SW620 cells (106 cells) were injected s.c. into the right flank of naive CD-1 nude mice. At 10 days after implantation, RCN-gfp (107 pfu) was injected into the tumor. RCNV was also injected at days 14, 17, and 24 after tumor implantation. Mice were followed until end point that was based on high tumor volume (P = 0.047). PBS, phosphate-buffered saline; pfu, plaque-forming unit; RCNV, Raccoonpox virus.
