Research Abstract |
Calcifying cystic odontogenic tumor (CCOT) is histopathologically characterized by the emergence of ghost cells. However, their histopathogenesis has been poorly understood. To understand the cellular mechanism towards ghost cell formation, we have successfully established of cell lines from a CCOT surgical specimen. Using these CCOT cells, we successfully demonstrated that ghost cells were generated due to intracellular deposits of extracellular matrix molecules including perlecan, and that their calcification was started in those matrices and completed by proteolysis of deposited matrices towards their denucleated forms.
