Activity of 25-Hydroxylase in Human Gingival Fibroblasts and Periodontal Ligament Cells
BACKGROUND We previously demonstrated that 25-hydroxyvitamin D(3) concentrations in gingival crevicular fluid are 300 times higher than those in the plasma of patients with aggressive periodontitis. Here we explored whether 25-hydroxyvitamin D(3) can be synthesized by periodontal soft tissue cells. We also investigated which of the two main kinds of hydroxylases, CYP27A1 and CYP2R1, is the key ...
متن کاملA comparative study of human periodontal ligament cells and gingival fibroblasts in vitro.
Both periodontal ligament and gingival tissue are thought to harbor cells with the ability to stimulate periodontal regeneration, i.e., formation of new bone, cementum, and connective tissue attachment. To understand further the role of these cells in the regenerative process, we compared human periodontal ligament cells and gingival fibroblasts, both derived from the same patient, same passage...
متن کاملFunctional characteristics of gingival and periodontal ligament fibroblasts.
In periodontal surgery, healing after guided tissue regeneration (GTR) may be explained by differences in functional activities of gingival and periodontal ligament fibroblasts (GF and PDLF). Several studies in vitro have supported this hypothesis, but much remains to be defined. In the present work, gingival and periodontal ligament fibroblasts derived from five healthy subjects were isolated ...
متن کاملIdentification of marker genes distinguishing human periodontal ligament cells from human mesenchymal stem cells and human gingival fibroblasts.
BACKGROUND AND OBJECTIVE Molecular gene markers, which can distinguish human bone marrow mesenchymal stem cells from human fibroblasts, have recently been reported. Messenger RNA levels of tissue factor pathway inhibitor-2, major histocompatibility complex-DR-alpha, major histocompatibility complex-DR-beta, and neuroserpin are higher in human bone marrow mesenchymal stem cells than in human fib...
متن کاملRole of HMGB1 in proliferation and migration of human gingival and periodontal ligament fibroblasts.
High mobility group box 1 (HMGB1) was originally defined as a nuclear protein. However, later studies showed that HMGB1 was released from damaged cells into the extracellular milieu and functioned as a danger signaling molecule. HMGB1 has also been shown to exert proliferative and chemoattractant effects on many cell types. In this study, we investigated the in vitro effect of human recombinant...
