Development of Novel Biocomposite Scaffold of Chitosan-Gelatin/Nanohydroxyapatite for Potential Bone Tissue Engineering Applications
In this study, a three-dimensional chitosan-gelatin/nanohydroxyapatite (ChG/nHaP) scaffold was successfully fabricated and characterized in terms of swelling, degradation, cell proliferation, cell attachment, and mineralization characterizations. The ChG/nHaP scaffold was fabricated with a mean pore size of 100-180 μm. Our results showed that the physicochemical and biological properties of the...
متن کاملSubchondral bone marrow lesions associated with knee osteoarthritis.
Knee osteoarthritis (OA) is a prevalent condition typically measured by the level of joint space thinning. However, it has been shown that the degree of joint space narrowing correlates poorly with the incidence and magnitude of knee pain. A review of recent and past literature suggests that chronic bone marrow edema (BME) or bone marrow lesions may be linked to pain, the progression of cartila...
متن کاملchitosan and nanohydroxyapatite roles in physical and chemical characteristics of gelatin/chitosan/nanohydroxyapatite microspheres
the effects of chitosan/biopolymer (c/p) and nanohydroxyapatite/ biopolymer (nha/p) weight ratios on particle size and its uniformity, cross-linking density and nh2 content of nano-hydroxyapatite/chitosan/gelatin (nha/c/g) microspheres were investigated. microspheres were fabricated using water-in-oil emulsion. cross-linking of microspheres was performed using water soluble carbodiimide. partic...
متن کاملPosttraumatic cyst-like lesions of cortical bone in children.
Cyst-like cortical defects appearing after minor greenstick fractures in children have occasionally been described. These lesions are asymptomatic and appear just proximal to the fracture line within the area of subperiostal new bone formation. Although the pathogenesis of these lesions remains conjectural, complete resolution occurs, without adverse effect on fracture healing. Only a few cases...
متن کاملBone repair by periodontal ligament stem cellseeded nanohydroxyapatite-chitosan scaffold
BACKGROUND A nanohydroxyapatite-coated chitosan scaffold has been developed in recent years, but the effect of this composite scaffold on the viability and differentiation of periodontal ligament stem cells (PDLSCs) and bone repair is still unknown. This study explored the behavior of PDLSCs on a new nanohydroxyapatite-coated genipin-chitosan conjunction scaffold (HGCCS) in vitro as compared wi...
