Isolated syngeneic epiphyseal chondrocytes transplanted into a muscle formed cartilage in which matrix resorption and endochondral ossification began at the end of the second week after transplantation. After 56 days cartilage was converted into an ossicle. In 7-day-old intrarenal transplants, epiphyseal chondrocytes formed nodules of cartilage. In 10-day-old transplants, islands of bone appear...
Fracture healing is a complex regenerative process. Although the histology and general mechanism of repair process are already clear and well established, much remains to be understood about the process of bone healing. The source of the cells that initiate fracture repair are unclear. It is thoght that fracture repair is initiated by mesenchymal progenitor cells (MPCs) which undergo differenti...
Background and Objective: One of the major concerns of surgeons and patients is repairing of bone loss due to various factors. Many materials have been made to improve the quantity and quality of bone loss repair. The aim of this research was radiographic evaluation of healing process of human bone loss created after implantation of HECBMG (Human Endochondral Bone Matrix Gelatin) and DBM (Demin...
Several growth factors are expressed in distinct temporal and spatial patterns during fracture repair. Of these, vascular endothelial growth factor, VEGF, is of particular interest because of its ability to induce neovascularization (angiogenesis). To determine whether VEGF is required for bone repair, we inhibited VEGF activity during secondary bone healing via a cartilage intermediate (endoch...
Vascular endothelial growth factor (VEGF)-mediated angiogenesis is an important part of bone formation. To clarify the role of VEGF isoforms in endochondral bone formation, we examined long bone development in mice expressing exclusively the VEGF120 isoform (VEGF120/120 mice). Neonatal VEGF120/120 long bones showed a completely disturbed vascular pattern, concomitant with a 35% decrease in trab...
PURPOSE The main purpose of the present clinical study was to compare architectural metric parameters using micro-computed tomography (μ-CT) between sites grafted with blocks harvested from the intramembranous origin calvarium and endochondral origin iliac crest for horizontal bone augmentation in the maxilla. The second aim was to compare primary stability of implants placed in both types of b...
Runx2 is a transcription factor prerequisite for chondrocyte maturation and osteoblast differentiation. We tested the hypothesis that Runx2 is responsible for signaling chondrocyte maturation and endochondral ossification in the condyle during mandibular advancement. Fifty 35-day-old Sprague-Dawley rats were fitted with functional appliances for 3, 7, 14, 21, and 30 days. Experimental animals w...
Following bone fracture, the repair process starts with an inflammatory reaction at the fracture site. Fracture healing is disturbed when the initial inflammation is increased or prolonged, whereby, a balanced inflammatory response is anticipated to be crucial for fracture healing, because it may induce down-stream responses leading to tissue repair. However, the impact of the immune response o...
