In order to investigate the consequences on the distribution of cell recovery through a cross-section of articular cartilage, the pathway for ice nucleation and diffusion of water and solutes in porcine osteochondral tissue was altered by drilling a 2mm diameter hole through the subchondral bone to the base of the cartilage. Samples equilibrated with 1M dimethyl sulfoxide were cooled at 1°C/min to -30°C then stored in liquid nitrogen. The most significant change due to bone base modification was an increase in recovery in the middle section of the cartilage, providing insights into mechanisms of cryoinjury in tissue systems.

More about this publication?
  • CryoLetters is a bimonthly international journal for low temperature sciences, including cryobiology, cryopreservation or vitrification of cells and tissues, chemical and physical aspects of freezing and drying, and studies involving ecology of cold environments, and cold adaptation

    The journal publishes original research reports, authoritative reviews, technical developments and commissioned book reviews of studies of the effects produced by low temperatures on a wide variety of scientific and technical processes, or those involving low temperature techniques in the investigation of physical, chemical, biological and ecological problems.
