TF and neoplasm: We and others have developed monoclonal antibodies towards TF (Clausen et al. 1988; Karsten et al. 1995; Goletz et al. 2003) and examined its expression on different types of tumor tissues (Itzkowitz et al. 1989; Langkilde et al. 1992; Cao et al. 1995; Cao et al. 1999; Cao et al. 2000; Baldus et al. 2000; Goletz et al. 2003; Cao et al. 2008) as compared to their corresponding normal tissues (Cao et al. 1996).
