title: Lectin-binding patterns in epithelial lining of jaw cysts.
abstract: Lectin-binding patterns were examined in epithelial walls of 65 jaw cysts (30 post-operative maxillary cysts: POMCs, 20 radicular and 15 follicular cysts), and characteristic lectin staining for each kind of jaw cysts is presented. Between squamous and columnar epithelia, the staining intensity of WGA, Con A and UEA-I was not different, but SBA bound more remarkably to squamous than to columnar epithelia. In both epithelia the outer layers did react more strongly with the lectins examined. Concerning odontogenic cysts, the lectin-binding affinities of outer and intermediate layer cells were nearly the same in both follicular and radicular cysts. Basal cells of radicular cyst walls were however, more markedly positive for lectin binding than of follicular cysts. Furthermore, basal cells of keratinized (RKSE 60 keratin-positive) epithelium were inferior to those of non-keratinized linings in the bindings. Lectin-binding patterns of metaplastic squamose epithelia of POMCs which were positive for RGE53-keratin (principally columnar epithelium-specific keratin) were similar to originally squamous linings of odontogenic cysts. Columnar linings of unusual radicular cysts were positively stained with SBA. By these results, lectin-binding sugar residues of the epithelium seem to be related to the epithelial morphology.
