Tumor angiogenesis in keratocystic odontogenic tumor assessed by using CD-105 antigen

The result suggests that CD105 (endoglin) is strongly expressed in microvessels of KCOT compared with that in Dentigerous cyst and Normal oral mucosa. Thus, it suggests that angiogenesis may be associated with locally aggressive biological behavior of KCOT. These findings further stress on the hypothesis that the stroma of KCOT could be regarded not just as a structural support of the cyst wall, but as playing a part in the neoplastic behavior of cyst.
