Design and Characterisation of a Multi-Layered Collagen-Based Scaffold for Osteochondral Defect Repair
Introduction Articular cartilage is a highly specialised tissue which is organised into distinct layers that vary in both structure and composition according to distance from the surface. Cartilage has a poor ability to regenerate itself and as a result, superficial damage almost inevitably leads to the development of osteoarthritis (OA). Recently, the potential of osteochondral tissue engineer...
متن کاملUse of allogeneic scaffold-free chondrocyte pellet in repair of osteochondral defect in a rabbit model.
Cell-based therapies are currently being used in treating osteochondral defect (OCD), but technical advances are needed to tackle the problems of scaffold and grafting technique. This study aimed to test the potential of allogeneic scaffold-free bioengineered chondrocyte pellet (BCP) in treating OCD. BCP was fabricated from rabbit costal cartilage and implanted into 3 mm × 3 mm OCD in medial fe...
متن کاملPrediction of the optimal mechanical properties for a scaffold used in osteochondral defect repair.
The optimal mechanical properties of a scaffold to promote cartilage generation in osteochondral defects in vivo are not known. During normal daily activities cartilage is subjected to large cyclic loads that not only facilitate nutrient transport and waste removal through the dense tissue but also act as a stimulus to the chondrocytes. In contrast, cartilage tissue is commonly engineered in vi...
متن کاملMarine Spongin: Naturally Prefabricated 3D Scaffold-Based Biomaterial
The biosynthesis, chemistry, structural features and functionality of spongin as a halogenated scleroprotein of keratosan demosponges are still paradigms. This review has the principal goal of providing thorough and comprehensive coverage of spongin as a naturally prefabricated 3D biomaterial with multifaceted applications. The history of spongin's discovery and use in the form of commercial sp...
متن کاملBiomimetic biphasic scaffolds for osteochondral defect repair
The osteochondral defects caused by vigorous trauma or physical disease are difficult to be managed. Tissue engineering provides a possible option to regenerate the damaged osteochondral tissues. For osteochondral reconstruction, one intact scaffold should be considered to support the regeneration of both cartilage and subchondral bone. Therefore, the biphasic scaffolds with the mimic structure...
