TF and age-related macular degeneration: The TF expression is detected on endothelial cells of pathological capillary blood vessels associated with solid tumours (Contrino et al, 1996; Shoji et al, 1998; Hu et al, 1999; Hu and Garen, 2001; Tang et al, 2007), wet macular degeneration (wMD) (Bora et al, 2003; Tezel et al, 2007) and endometriosis (Krikun et al, 2010); however, TF is not expressed on endothelial cells of normal blood vessels (Drake et al, 1989; Flossel et al, 1994; Contrino et al, 1996; Hu et al, 1999; Hu and Garen, 2001).
