Odontogenic cysts are non-neoplastic lesions that form as a consequence of the proliferation of epithelial residues that remain embedded in the maxillary bones after formation of dental tissues. The epithelial rests proliferate in response to activating cell mediator signals released during inflammatory processes (for example as a consequence of a tooth infection). In this report we discuss the...

PURPOSE Collagen XVIII is expressed in ocular basement membranes (BMs) and inactivating mutations cause Knobloch syndrome, with several ocular abnormalities. In this study we investigated ocular structures in collagen XVIII/endostatin (Col18a1(-/-))-deficient mice to elucidate the role of this extracellular matrix component in the eye. METHODS Eyes of Col18a1(-/-) and control mice were examin...
