Figure 1 illustrates GB blood vessels with weak (1E) and strong (1F) vascular staining intensity of ICAM-1. Individual mean values for ICAM-1 intensity were from 1.2 to 2.9. Group mean value was 1.8 ± 0.4 (mean ± SD) and the median value was 1.7. In contrast to CD133, between the number of visible blood vessels and vascular ICAM-1 staining intensity, a negative correlation was detected (p = 0.04); that is, in tumor samples with strong ICAM-1 staining, fewer blood vessels were seen. The gene discussed is PROM1; the disease is neoplasm.
