Identification of molecules associated with the development of metastasis in human malignant melanoma

Differential antibody reactivity has been used to identify molecules which change in expression or which are modified during tumor progression in human malignant melanoma. Such molecules may play a role in the development of the metastatic capacity of this tumor. Two of these molecules (ICAM-1 and MUC18) have been identified as cell adhesion molecules which are potentially involved in tumor-leukocyte-endothelial interactions.
