Peri‐prosthetic tissue cells show osteogenic capacity to differentiate into the osteoblastic lineage
During the process of aseptic loosening of prostheses, particulate wear debris induces a continuous inflammatory-like response resulting in the formation of a layer of fibrous peri-prosthetic tissue at the bone-prosthesis interface. The current treatment for loosening is revision surgery which is associated with a high-morbidity rate, especially in old patients. Therefore, less invasive alterna...
An exogenous supply of bone morphogenetic protein 2 (BMP2) and vascular endothelial growth factors 165 (VEGF165) will synergize to promote bone regeneration in vivo. The aim of this study was to confirm the role of VEGF165 on the osteogenesis potential of bone mesenchymal stem cells (BMSCs) transduced by adenovirus vector containing BMP2 gene in vitro.Rabbit BMSCs were isolated and transfected ...
The two marine inorganic polymers, biosilica (BS), enzymatically synthesized from ortho-silicate, and polyphosphate (polyP), a likewise enzymatically synthesized polymer consisting of 10 to >100 phosphate residues linked by high-energy phosphoanhydride bonds, have previously been shown to display a morphogenetic effect on osteoblasts. In the present study, the effect of these polymers on the di...
The goal of these studies was to investigate the effect of resveratrol treatment on the osteogenic potential of human and rat adipose derived stem cells both in a 2-D and 3D culture environment. Adipose derived stem cells (ADSCs) have shown promise as a potential source of osteogenic progenitor cells. Resveratrol has been shown to inhibit adipogenic differentiation while simultaneously activati...
Bone tissue engineering is a promising field of regenerative medicine in which cultured cells, scaffolds, and osteogenic inductive signals are used to regenerate bone. Human bone marrow stromal cells (BMSCs) are the most commonly used cell source for bone tissue engineering. Although it is known that cell culture and induction protocols significantly affect the in vivo bone forming ability of B...
STUDY DESIGN Basic experiments in a mouse model of ossification of the posterior longitudinal ligament (OPLL). OBJECTIVE To assess the osteogenic potential of mesenchymal stem cells (MSCs) obtained from muscle and adipose tissue in Tiptoe-walking (ttw) mice, in which cervical OPLL compresses the spinal cord and causes motor and sensory dysfunction. SUMMARY OF BACKGROUND DATA In humans, MSCs...
Nonunion is a serious complication of a bone fracture that may occur in any bone of the skeletal system. It occurs when a broken bone fails to heal. Mesenchymal stem cell (MSC)-based tissue engineering technology has been considered an efficient method to improve the healing rate of nonunions. Although previous studies have demonstrated that bone morphogenetic protein 9 (BMP9) is highly capable...
Hydroxyapatite (HA), the principal component of bone mineral, shows osteoconductive properties when employed for coating metal implants as well as scaffold materials in synthetic bone grafts. With the goal of providing this material with osteoinductive capabilities to promote faster bone regeneration, we show an easy approach to functionalize HA implant surfaces and enrich them with osteoinduct...
