Periodontal Ligament Cells are Chemotactic to Fibroblast Collagenase
Journal of Dental Research, 1996Periodontal ligament (PDL) cell motility and the passage of PDL cells along a root surface are important components of tissue remodeling during periodontal regeneration. Proteolytic enzymes, including fibroblast collagenase, have been demonstrated to play an important role in tissue remodeling. Previous studies have shown that PDL cells chemotactically

Periodontal ligament stem cells: an update and perspectives
Journal of Investigative and Clinical Dentistry, 2014AbstractChronic periodontitis is a serious infectious and inflammatory oral disease of humans worldwide. Conventional treatment modalities are effective for controlling periodontal disease. However, the regeneration of damaged periodontal tissues remains a major challenge in clinical practice due to the complex structure of the periodontium.

Immortalized cementoblasts and periodontal ligament cells in culture
Bone, 1999Cementum, a mineralized tissue lining the surface of the tooth root, is required for formation of a functional periodontal ligament attachment during development. Additionally, during regeneration of tissues after disease, cementum is thought to play a critical role in the reparative process.

Human periodontal ligament cells in vitro
Journal of Periodontal Research, 1987This paper reports on ultrastructural features of human periodontal ligament (PDL) cells growing in vitro as primary outgrowths and as continuous lines. The two most striking features of these cells were: 1) their branching bands of micro filaments containing semiperiodic dense nodes; and 2) the massive amounts of glycogen (α and β particles) found in ...

Characteristics of human periodontal ligament cells in vitro
Archives of Oral Biology, 1990Periodontal ligament cells may have a role in the regulation of hard and soft periodontal tissues, but their specific function has yet to be determined. To evaluate further their role in periodontal homeostasis, they were examined for osteoblast-like behaviour; in vitro no characteristic osteoblastic responsiveness was found. Periodontal ligament cells

Progenitor cell populations in the periodontal ligament of mice
The Anatomical Record, 1985AbstractStem cells in a variety of renewal tissues exhibit a slow rate of cell proliferation (Potten et al., 1979). The periodontal ligament of mouse molars was examined for the presence of slowly cycling progenitor cells to provide evidence for the existence of stem cells in this tissue. A pulse injection of 3H‐thymidine was administered and mice were

Flow Cytometry Analysis of Gingival and Periodontal Ligament Cells
Journal of Dental Research, 1998Gingival and periodontal ligament (PDL) fibroblasts are the major cellular components of periodontal soft connective tissues, but the precise differences between these cells are not yet known. In the present study, we have therefore examined the phenotypic and functional features of the cells obtained from gingival and PDL biopsy samples.

Cell rests in the periodontal ligament of mouse molars
Journal of Periodontal Research, 1975Recent reports have indicated that Hertwig's epithelial root sheath in rats and mice becomes trapped between dentin and cementum or within cementum during molar root development. Evidence is presented that well defined cell rests persist nevertheless in the periodontal ligament of mouse molars. These rests are located in close proximity to the cementum

Cell division and periodontal ligament formation in the mouse
Archives of Oral Biology, 1972Abstract Twelve-day-old mice were injected with 5 μCi/g body weight of tritiated thymidine and killed 3, 24 and 72 hr after injection. Autoradiographs were prepared of serial bucco-lingual sections through the developing ligament of the first mandibular molar.

[In vitro study of periodontal ligament cells].
Minerva stomatologica, 2000The aim of this research is to outline a procedure able to promote specific cellular differentiation and proliferation with consequent periodontal regeneration. To achieve this goal, use was made of various compounds supposed to have the capacity of aiding periodontal regeneration.The cells utilised for this study were obtained from explants of human ...
