1. Topical application of bFGF on acid-conditioned and non-conditioned dentin: effect on cell proliferation and gene expression in cells relevant for periodontal regeneration
Abstract Periodontal regeneration is still a challenge in terms of predictability and magnitude of effect. In this study we assess the biological effects of combining chemical root conditioning and biological mediators on three relevant cell types for periodontal regeneration. Material and Methods: Bovine dentin slices were conditioned with 25% citric acid

2. Fluoxetine effects on periodontogenesis: histomorphometrical and immunohistochemical analyses in rats
Abstract Reports have indicated that serotonin plays an important role in cell migration and differentiation during the organogenesis of several tissues, including the oral types. Administration of selective serotonin reuptake inhibitor (SSRI) drugs during pregnancy could affect the delivery of serotonin to embryonic tissues altering its development. Object

3. Effects of IL-10 and glucose on expression of OPG and RANKL in human periodontal ligament fibroblasts
The effects of interleukin-10 (IL-10) and glucose on mRNA and protein expression of osteoprotegerin (OPG), and its ligand, receptor activator of nuclear factor-κB ligand (RANKL), were investigated in human periodontal ligament fibroblasts (HPDLFs). Primary HPDLFs were treated with different concentrations of IL-10 (0, 1, 10, 25, 50, and 100 ng/mL) or glucos

6. Expression of osteoblastic phenotype in periodontal ligament fibroblasts cultured in three-dimensional collagen gel
Objective : To investigate the influence of a three-dimensional cell culture model on the expression of osteoblastic phenotype in human periodontal ligament fibroblast (hPDLF) cultures. Material and Methods : hPDLF were seeded on bi-dimensional (2D) and three-dimensional (3D) collagen type I (experimental groups) and and on a plastic coverslip (control) for

7. Advanced glycation end products (AGEs) and their receptor (RAGE) induce apoptosis of periodontal ligament fibroblasts
Diabetics have an increased prevalence of periodontitis, and diabetes is one of the causative factors of severe periodontitis. Apoptosis is thought to be involved in this pathogenic relationship. The aim of this study was to investigate apoptosis in human periodontal ligament (PDL) fibroblasts induced by advanced glycation end products (AGEs) and their recep

9. Expressão dos fenótipos fibroblástico e osteoblástico em culturas tridimensionais na presença de partículas de vidro bioativo / Osteoblastic and fibroblastic phenotypes expression on three dimensional cell cultures in the presence of bioactive glass particles
O objetivo deste estudo foi analisar a expressão dos fenótipos fibroblástico e osteoblástico em culturas tridimensionais na presença ou não de partículas de vidro bioativo. Fibroblastos derivados do ligamento periodontal humano (hPDLF) e células osteogênicas da calvária de rato recém-nascidos foram plaqueadas em superfícies bidimensionais - lamí

10. Estudo da expressão e produção de componentes do sistema renina-angiotensina por fibroblastos de gengiva e ligamento periodontal humanos / Study of expression and production of the renin-angiotensin system components by gingival and periodontal ligament human fibroblasts
O Sistema Renina-angiotensina (SRA), e um sistema capaz de gerar hormonios peptideos com grande impacto na regulacao cardiovascular e na patogenese das doencas cardiovasculares. Este sistema opera, por meio das acoes da Angiotensina II, tanto em nivel sistemico (endocrino) quanto tecidual (local, paracrino/autocrino) controlando importantes funcoes, varias d

12. Estudo in vitro da produção de quimiocinas e pró-colágeno I por fibroblastos de gengiva, ligamento periodontal e polpa dental humanos / In vitro study of chemokines and procollagen I by human gingival, periodontal ligament and dental pulp fibroblasts
Fibroblastos são as células mais numerosas encontradas nos tecidos orais como gengiva, ligamento periodontal e polpa dental. Além de exercerem função estrutural, estas células também desempenham papel importante na resposta imune destes tecidos através do reconhecimento de antígenos e produção de mediadores inflamatórios e citocinas.
