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.
Large articular cartilage defects have proven difficult to treat and often result in osteoarthritis of the affected joint. Cryopreservation of articular cartilage can provide an increased supply of tissues for osteochondral allograft but cryoprotective agents are required; however, few studies...
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...
The multisolute osmotic virial equation is the only multisolute thermodynamic solution theory that has been derived from first principles and can make predictions of multisolute solution behaviour in the absence of multisolute solution data. Other solution theories either (i) include simplifying...
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....
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...
Investigating cryoinjury using simulations and experiments: 1. TF-1 cells during two-step freezing (rapid cooling interrupted with a hold time)Download
There is significant interest in designing a cryopreservation protocol for hematopoietic stem cells (HSC) which does not rely on dimethyl sulfoxide (Me2SO) as a cryoprotectant. Computer simulations that describe cellular osmotic responses during cooling and warming can be used to optimize the...
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...
Investigating cryoinjury using simulations and experiments: 2. TF-1 cells during graded freezing (interrupted slow cooling without hold time)Download
Cryopreservation plays a key role in the long-term storage of native and engineered cells and tissues for research and clinical applications. The survival of cells and tissues after freezing and thawing depends on the ability of the cells to withstand a variety of stresses imposed by the...
