Human Periodontal Fibroblast Response to Enamel Matrix Derivative, Amelogenin, and Platelet-Derived Growth Factor-BB

Molecular mechanisms of angiogenic synergism between Fibroblast Growth Factor-2 and Platelet Derived Growth Factor-BB

Periodontal regeneration in humans using recombinant human platelet-derived growth factor-BB (rhPDGF-BB) and allogenic bone.

BACKGROUND Purified recombinant human platelet-derived growth factor BB (rhPDGF-BB) is a potent wound healing growth factor and stimulator of the proliferation and recruitment of both periodontal ligament (PDL) and bone cells. The hypothesis tested in this study was that application of rhPDGF-BB incorporated in bone allograft would induce regeneration of a complete new attachment apparatus, inc...

Enamel matrix derivative stimulates human gingival fibroblast proliferation via ERK.

Emdogain, a formulation of Enamel Matrix Proteins, is used clinically for periodontal regeneration to stimulate PDL (periodontal ligament), cementum, and bone formation. Its effects on gingival fibroblasts and tissue have not been thoroughly studied. Therefore, we investigated the mechanisms by which Emdogain affects the cell cycle of human gingival fibroblasts. Without serum, Emdogain (50 micr...

Mechanism of human dermal fibroblast migration driven by type I collagen and platelet-derived growth factor-BB.

Migration of human dermal fibroblasts (HDFs) is critical for skin wound healing. The mechanism remains unclear. We report here that platelet-derived growth factor-BB (PDGF-BB) is the major promotility factor in human serum for HDF motility on type I collagen. PDGF-BB recapitulates the full promotility activity of human serum and anti-PDGF neutralizing antibodies completely block it. Although co...

Periodontal regeneration in human Class II furcations using purified recombinant human platelet-derived growth factor-BB (rhPDGF-BB) with bone allograft.

This human clinical trial evaluated the clinical and histologic response to recombinant human platelet-derived growth factor-BB (rhPDGF-BB) delivered in bone allograft for the treatment of advanced Class II furcation defects. Three mandibular and one maxillary molar furcation defects were treated: Two received 0.5 mg/mL and two received 1.0 mg/mL rhPDGF-BB, in all cases mixed with DFDBA. Clinic...
