| Research Abstract |
We hypothesized that tumor-associated endothelial cells (TEC) facilitate tumor metastasis. We established TEC from xenograft tumor of the low metastatic malignant melanoma cell , A375 and from that of high metastatic counter part, A375SM("super metasitatic"). Comparison of those 2 TEC revealed specific up regulation of some microRNA in A375SM TEC. Transfection of the microRNA change the phenotype of normal endothelial cells from normal skin to that of A375SM TEC.
