Gingival fibroblast response to cyclosporin A and transforming growth factor beta(1)

Research output: Contribution to journalArticlepeer-review

Abstract

This study investigates a potential role for TGF beta(1), in the pathogenesis of cyclosporin A-induced gingival overgrowth (CsA-OG). TGF beta(1) was localized immunohistochemically in the connective tissue of both normal gingiva and CsA-OG. Intense staining for TGF beta(1) was detected at the tips of the dermal papillae of the overgrown gingiva. In addition, fibroblasts derived from healthy gingiva and fibroblasts derived from CsA-OG were cultured both as monolayers or embedded in a 3D-collagen gel. Fibroblast activity was monitored in terms of protein and collagen production in the presence of (i) 1 ng/ml TGF beta(1), (ii) 500 ng/ml CsA, or (iii) 500 ng/ml CsA and 1 ng/ml TGF beta(1). In monolayer culture TGF beta(1) significantly increased protein and collagen production in all cell strains (p
