【Abstract】 ? Objective To investigate the angiogenic effect of ICAM 1. Method human dermal hemangioma specimens, in which 17 were in the proliferating phase and 11 in the involuting phase, were detected with immunohistochemical technique for ICAM 1. Result ICAM 1 was localized on proliferating endothelial cells of microvessels; the mean optical density and the rate of positive area in proliferating hemangiomas were significantly higher than those in involuting hemangiomas ( P <0 01); and the expression of ICAM 1 increased during lumen formation of microvessles. Conclusion These results suggest that ICAM 1 plays a role in angiogenesis.\;〔更多还原
