(b) Our preliminary quantitative results of the vascular density (Figure 8) of the SC tumors supports the second aspect that METCAM/MUC18 induces tumor dormancy by the suppression of angiogenesis; however, a definitive conclusion must await future systematic investigations by immune-staining of blood and lymphatic vessels and vasculogenic mimicries with specific antibodies. The gene discussed is MCAM; the disease is neoplasm.
