Likewise, a significant suppression of tumor cell proliferation (mean number of cells stained positive for Ki-67: therapy group 1754 ± 184, control group 2883 ± 323, p = 0.012) and tumor vascularity (mean number of cells stained positive for CD31: therapy group 107 ± 10, control group 182 ± 22, p = 0.006) was observed. This evidence concerns the gene PECAM1 and neoplasm.
