Autologous cartilage fragments in a composite scaffold for one stage osteochondral repair in a goat model.
We propose a culture-free approach to osteochondral repair with minced autologous cartilage fragments loaded onto a scaffold composed of a hyaluronic acid (HA)-derived membrane, platelet-rich fibrin matrix (PRFM) and fibrin glue. The aim of the study was to demonstrate in vitro the outgrowth of chondrocytes from cartilage fragments onto this scaffold and, in vivo, the formation of functional re...
متن کاملSpontaneous repair of full-thickness defects of articular cartilage in a goat model. A preliminary study.
BACKGROUND Full-thickness defects measuring 3 mm in diameter have been commonly used in studies of rabbits to evaluate new procedures designed to improve the quality of articular cartilage repair. These defects initially heal spontaneously. However, little information is available on the characteristics of repair of larger defects. The objective of the present study was to define the characteri...
متن کاملDecellularized Cartilage as a Bioactive Biomaterial for Cartilage Tissue Engineering
Cartilage matrix is a particularly promising acellular material for cartilage regeneration given the evidence supporting its chondroinductive character. The ‘raw materials’ of cartilage matrix can serve as building blocks and signals for enhanced tissue regeneration. These matrices can be created by chemical or physical methods: physical methods disrupt cellular membranes and nuclei but may not...
متن کاملDevelopment and characterisation of a decellularised bovine osteochondral biomaterial for cartilage repair
It is proposed that an acellular natural osteochondral scaffold will provide a successful repair material for the early intervention treatment of cartilage lesions, to prevent or slow the progression of cartilage deterioration to osteoarthritis. Here, we investigated the efficacy of methods for the decellularisation of bovine osteochondral plugs. The plugs were subject to four freeze/thaw cycle...
متن کاملThe Role of Gene Therapy in Cartilage Repair
The key principle of gene delivery to articulations by direct intra-articular injection is to release complementary DNA(cDNA)-encoding medical products that will lead to maintained, endogenous production of the gene products withinthe articulation. In fact, this has been accomplished for both in vivo and ex vivo gene delivery, using several vectors,genes, and cells in some animal models. Some c...
