A marker for new blood vessel formation in tumors
...aubner and colleagues' work, in a mouse with human melanoma
and in a small study of patients with tumors including melanoma, suggests that the marker is truly reflecting the in vivo level of the integrin. Hence the marker could be used to identify tumors that express this marker, assess the degree of new vess...
