We quantitatively studied the role of periosteum and bone marrow-endosteum during lengthening in 18 growing rabbits, comparing four surgical procedures: 1) periosteum and bone marrow preservation, 2) periosteum preservation, bone marrow destruction, 3) periosteum destruction, bone marrow preservation, 4) periosteum and bone marrow destruction. An external fixator was set on one femur, the other...
PURPOSE Pluripotent cells residing in the periosteum, a bi-layered membrane enveloping all bones, exhibit a remarkable regenerative capacity to fill in critical sized defects of the ovine femur within two weeks of treatment. Harnessing the regenerative power of the periosteum appears to be limited only by the amount of healthy periosteum available. Here we use a substitute periosteum, a deliver...
BACKGROUND To compare the different resorption patterns between resorbable membrane barrier and periosteum after iliac block bone grafting radiographically and histologically. METHODS Eighteen mature male rabbits weighing from 2.0 to 2.5 kg were used. The recipient site was the rabbit skull, and autogenous iliac bone was used as the grafting material. The harvested iliac block bones were divi...
The ultimate goal of any dental treatment is the regeneration of lost tissues and alveolar bone. Under the appropriate culture conditions, periosteal cells secrete extracellular matrix and form a membranous structure. The periosteum can be easily harvested from the patient's own oral cavity, where the resulting donor site wound is invisible. Owing to the above reasons, the periosteum offers a r...
The periosteum supplies osteoblasts and nutrients for bone metabolism and is important for osteoblast differentiation and osteogenesis. Recently, periosteum-derived cells have been used for orofacial bone regeneration therapy. However, little is known about the function of the periosteum in physiological bone remodeling. On our hypothesis that the periosteum senses a mechanical stress to induce...
Perichondrium/periosteum is involved in regulating long bone growth. Long bones grow faster after removal or circumferential division of periosteum. This can be countered by culturing them in conditioned medium from perichondrium/periosteum cells. Because both complete removal and circumferential division are effective, we hypothesized that perichondrium/periosteum cells require an intact envir...
Cigarette smoke is associated with delayed fracture healing, alterations in mineral content, and osteoporosis, however, its effects on osteoblastic differentiation of osteoprogenitor cells are not fully understood. In the present study, we examined the effects of cigarette smoke extract (CSE) on osteoblastic differentiation of cultured human periosteum-derived cells. We found that CSE inhibited...
Bone repair requires the mobilization of adult skeletal stem cells/progenitors to allow deposition of cartilage and bone at the injury site. These stem cells/progenitors are believed to come from multiple sources including the bone marrow and the periosteum. The goal of this study was to establish the cellular contributions of bone marrow and periosteum to bone healing in vivo and to assess the...
I previously reported that F-box/leucine-rich repeat protein 14 (FBXL14) expressed in periosteum-derived cells, and F-box WD-40 domain-containing 2 (FBXW2) the periosteum form a fiber-like structure. Here, two culture medium conditions, is, media with without ascorbic acid, were compared during explant culture. In absence of expression patterns osteocalcin, FBXW2, elastin using fluorescent immu...
