    Cell attachment activity of cementum: bone sialoprotein _ identified in cementum (1991)

    Notes: Considerable research effort has been directed at preparing root surfaces in a fashion that would promote cell attachment leading to periodontal regeneration; however, no methods have proven to be clinically predictable. Identification of attachment protein(s) associated with the root surface matrix of cementum may prove valuable for developing effective clinical treatments. In this study cementum proteins were extracted from bovine and human teeth by sequential chaotropic extraction using guanidine followed by guanidine/EDTA. The guanidine/EDTA extract, but not guanidine extract, was found to promote attachment of fibroblasts. This attachment activity was inhibitable with synthetic peptide containing the attachment sequence arginine-glycine-aspartic acid (RGD). Fractionation of the guanidine/EDTA extract revealed several fractions with attachment activity. Immunoblot analysis demonstrated that two of these fractions contain the bone-associated RGD containing attachment protein, bone sialoprotein-II (BSP-II). In addition, attachment activity was also noted in other fractions that could not be attributed to BSP-II or fibronectin. These studies indicate that a component of the attachment activity of cementum is likely to be due to BSP-II and that cementum contains additional, as yet undetermined, attachment proteins.

    Effects of minocycline on fibroblast attachment and spreading (1988)

    Notes: One of the initial events required for periodontal regeneration is the attachment and subsequent spreading of fibroblasts at the healing site (root surface). In order to further our understanding of the possible role of tetracyclines in connective tissue attachment, human gingival fibroblasts exposed to minocycline and tetracycline were evaluated for cell attachment and spreading properties in vitro. The results indicated that both minocycline and tetracycline enhanced cell attachment, but minocycline had greater efficacy. Enhanced cell attachment to polystyrene uncoated dishes was seen at a 20 μg/ml dose of minocycline, while maximum cell attachment was seen at 50 μg/ml. Exposure of cells to 200 μg/ml of minocycline resulted in a decline from maximum cell attachment. In addition, cell spreading was inhibited at the higher concentrations of drug. Cells exposed to 50 μg/ml of minocycline for 2 days had no change in total protein or collagen production when compared to control cells. This dose of minocycline had no effect on cell proliferation at 2 d, but over a 7-d time course there was a significant decline in cell proliferation. These findings are important to clinical assessment of tetracyclines and indicate that such evaluations should include establishment of doses that favor cell attachment and spreading.

    Expression of heat stress proteins by human periodontal ligament cells (1988)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of oral pathology & medicine 17 (1988), S. 0

    Notes: The purpose of the present report was to document the stress response produced by physical and chemical abuses to human periodontal ligament cells, and to review some of the known functions of stress response proteins produced as a result of such treatments. For these studies human PDL cells were exposed to sublethal challenges of 43°C heat, sodium arsenite and the amino acid analog L-azetidine-2-carboxylic acid (AZC). The cells were labelled with [35S]-methionine and the proteins produced were examined by autofluorography of SDS-PAGE gels. Heat challenges were shown to induce hsps with an apparent mol. wts. of 90K, 68-72K, 41–47K, and 36 K. Arsenite-treated cells produced similar hsps including a 30k protein not produced by other forms of stress. AZC treatment resulted in the production of apparent functionless hsps with apparent molecular weights of 90,000, 72,000, 68,000 and 36,000. The function of these proteins and their possible role in periodontal disease is discussed.

    Synthetic activities of mass cultures and clones of human gingival fibroblasts (1986)

    Notes: Summary The percentage of synthesis dedicated to collagen is elevated in low-density cultures of human gingival fibroblasts, as is per-cell total protein synthetic activity and glycosaminoglycan accumulation. These observations can be explained, in part, by a decrease in membrane transport of precursor substance in high-density cultures. Synthetic activity by human fibroblasts can be reliably assayed in vitro using as few as 500 cells sparsely seeded. Such low-cell number assay is essential for study of single-cell clones, where replicative life span is limited.
