Osteoarthritis, a disease resulting in the breakdown of cartilage and bone within joints, is a global burden that is growing in scope. There is no cure for osteoarthritis, and the current treatments are all lacking in some form or another. One treatment which attempts to prevent degeneration of...
Vitrification of articular cartilage (AC) could enhance tissue availability but requires high concentrations of cyroprotective agents (CPAs). This study investigated relative injuries caused by commonly used CPAs. We hypothesized that the in situ chondrocyte dose–injury relationships of five...
Objective: Osteochondral allografting is an effective method to treat large osteochondral defects but difficulties in tissue preservation have significantly limited the application of this technique. Successful cryopreservation of articular cartilage (AC) could improve the clinical availability...
In previous research, we successfully cryopreserved intact human articular cartilage on its bone base with high chondrocyte viability using a vitrification protocol that entailed sequential exposure to several cryopreserving agents (CPAs) at lowering temperatures resulting in a high final...
Background Vitrification is a method of cryopreservation by which cells and tissues can be preserved at low temperatures using cryoprotective agents (CPAs) at high concentrations (typically ⩾6.0 M) to limit the harmful effects of ice crystals that can form during cooling processes. However, at...
Articular cartilage injuries do not heal and large defects result in osteoarthritis with major personal and socioeconomic costs. Osteochondral transplantation is an effective treatment for large joint defects but its use is limited by the inability to store cartilage for long periods of time....
Statistical prediction of the vitrifiability and glass stability of multi-component cryoprotective agent solutions.Download
Long-term biologic storage of articular cartilage has proven elusive due to cellular degradation over time or acute damage during attempts at cryopreservation. Vitrification is one option that may result in successful cryopreservation but difficulty with cryoprotective agent (CPA) toxicity at...
This brief manuscript introduces the subject of thermodynamics and the papers of the special issue on thermodynamic aspects of cryobiology. Thermodynamic terminology is defined for the non-specialist.
