This study was undertaken to determine whether periosteum from different bone sources in a donor results in the same formation of bone and cartilage. In this case, periosteum obtained from the cranium and mandible (examples of tissue supporting intramembranous ossification) and the radius and ilium (examples of tissues supporting endochondral ossification) of individual calves was used to produ...
BACKGROUND The use of the Masquelet technique in the repair of large bone defects has gained increased acceptance in recent years. The core of this technique is the induction of granulation tissue membrane formation and the implantation of an autologous cancellous bone to reconstruct bone defects in the membrane. In this study, we purpose to explore the structure of induced membrane and the con...
We aimed to evaluate a new technique for intraoral expansion of soft tissue with a self-inflatable expander in rabbits. We placed a self-inflatable soft tissue expander bilaterally in eight rabbits under the periosteum of the mandible through an extraoral approach. The expander was left to self-inflate for two weeks, after which the animals were killed and specimens collected for histological e...
The periosteum plays an indispensable role in both bone formation and bone defect healing. In this study we constructed an artificial in vitro periosteum by incorporating osteogenic differentiated bone marrow stromal cells (BMSCs) and cobalt chloride (CoCl(2))-treated BMSCs. The engineered periostea were implanted both subcutaneously and into skull bone defects in SCID mice to investigate ectop...
An important consideration in regeneration therapy is the fact that the tissue surrounding an organ supports its function. Understanding the structure of the periosteum can contribute to more effective bone regeneration therapy. As a cellular source, the periosteum also assists bone growth and fracture healing; this further necessitates its direct contact with the bone. However, its anchoring s...
Periosteum is a source of osteoprogenitor cells and some investigators advocated the effective use of periosteum as a grafting material for the repair of bone and joint defects. In the present study, we showed bone formation induced from cultured periosteum-derived cells (CPDC) in the rat calvarial defect model. Periosteum taken from a rat tibia was immediately placed in culture medium with 10%...
This case series describes a modified technique for increasing the width of the attached gingiva (AG). The described technique is a variation of the apically repositioned flap technique previously proposed by Freidman in 1962. The modified apically repositioned flap (MARF) technique uses a single horizontal incision within the keratinized tissue (KT), elevating a split-thickness flap, and sutur...
PURPOSE The aim of the present study was to characterize the cell of the human periosteum using immunohistological and molecular methods. METHODS Phenotypic properties and the distribution of the cells within the different layers were investigated with immunohistochemical staining techniques and RT-PCR, focussing on markers for stromal stem cells, osteoblasts, osteoclasts and immune cells. ...
