Biomimetic Periosteum In article 2203027 by Yanlin Su, Kaifang Chen, Daping Quan, Xiaodong Guo, and co-workers, [email protected] electroactive biomimetic periosteum is created, which can regulate the concentration of axon initial segments in sensory nerves, promote bone regeneration releasing neuropeptides. This will enrich theory neurogenic provide a promising treatment for defects.

Tissue-engineered middle phalanx constructs of human digits were investigated to determine whether periosteum wrapped partly about model midshafts mediated cartilage growth plate formation. Models were fabricated by suturing ends of polymer midshafts in a human middle phalanx shape with polymer sheets seeded with heterogeneous chondrocyte populations from bovine articular cartilage. Half of eac...

OBJECTIVES The aim of this study is to compare the effect of extracorporeal shock wave therapy (ESWT) on fractures with intact periosteum and excised periosteum. MATERIALS AND METHODS Thirty-seven Wistar albino rats were randomized into four groups. Osteotomy and intramedullary Kirschner wire fixation were performed on all right femurs under ketamin anesthesia. The first group (n=10) was iden...

Background: We aimed to determine the expression of two neuropeptides, neuropeptide Y (NPY) and vasoactive intestine peptide (VIP), in the pathological tissues of congenital pseudarthrosis of the tibia (CPT) patients for understanding the etiology and pathogenesis of CPT. Methods: Periosteum and bone specimens from 20 CPT patients were studied, in comparison to 20 normal periosteum and bone tis...

Better understanding of bone growth and regeneration mechanisms within periosteal tissues will improve understanding of bone physiology and pathology. Macrophage contributions to bone biology and repair have been established but specific investigation of periosteal macrophages has not been undertaken. We used an immunohistochemistry approach to characterize macrophages in growing murine bone an...

INTRODUCTION The periosteum serves as a stabilizing boundary membrane to the bone it envelops and is known to contain pluripotent and osteochodroprogenitor cells. Periosteal cells have been shown to have the capacity to infill critical sized defects with proliferative woven bone within weeks of injury [1,2]. Critical sized defect healing has been shown to be maximal when cells egress from perio...

Introduction: Many pathological processes such as infections, intoxications, and malignant tumors were spread through the lymphatic vessels of thoracic cavity. In present study, we investigated anatomy lymph nodes cavity in humans.
 Materials methods: The examination was performed on 60 cadavers fetuses (25), newborn children (14), (11), adults (10). Lymphatic rib periosteum, costovertebra...

Fracture healing is a complex process that involves presence of osteoprogenitor cells and growth factors. Therefore, the integrity of the fracture site surrounding tissues including periosteum is necessary in order to provide the resources for bone regeneration. The purpose of this review is to organize and synthesize the relevant information regarding periosteum and fracture repair. Periosteum...

The periosteum is a thin layer of connective tissue that covers the outer surface of a bone in all places except at joints (which are protected by articular cartilage). As opposed to bone itself, it has nociceptive nerve endings, making it very sensitive to manipulation. It also provides nourishment in the form of blood supply to the bone. The periosteum is connected to the bone by strong colla...

PURPOSE The final goal of regenerative periodontal therapy is to restore the structure and function of the periodontium destroyed or lost due to periodontitis. However, the role of periosteum in periodontal regeneration was relatively neglected while bone repair in the skeleton occurs as a result of a significant contribution from the periosteum. The aim of this study is to understand the histo...
