EMB and neoplasm: As expected, the FM3A tumor samples from Hph-1-gp70-injected mice exhibited strong expression of gp70 (Figure 6A, bottom-right), whereas no gp70 expression was detected in Hph-1-GFP-injected mice (Figure 6A, top-right), which exhibited strong expression of GFP in tumor cells (Figure 6A, top-left).
