Cryo- & Cold-Management<br />

Cold- and cryo-preservation are critical steps while working with tissues and<br />

cells. Noteworthy to explain the importance of optimal, reproducible, and<br />

reliable cell work in clinical trials, cell therapies and regenerative medicine<br />

applications for humans and animals. It is obvious that basic research, drug<br />

development and compound testing will need the highest possible quality<br />

of cellular systems, too.<br />

Preservation is a critical, and often underappreciated, step in all research<br />

and clinical projects where tissues and cells will be used. It is best to optimize<br />

this process as early as possible to ensure reliable research, predictive<br />

compound testing, effective cellular therapies and highest possible<br />

cell/tissue quality.<br />

Cells can be isolated via cell separation (magnetic or non-magnetic procedures) or by tissue dissociation enzymes<br />

(collagenase & protease). In both cases the quality of cell source will be a critical factor. Cold preservation using special<br />

media which will help to keep the quality of tissues as high as possible. In many procedures cold- as well as cryo-preservation<br />

will be done.<br />

Cold-Preservation-Hypothermic Storage<br />

Storage of tissues and cells at low temperatures (4-10°C) for short periods (hours up to days) is defined as hypothermic<br />

storage. In the field of regenerative medicine cold preservation is an extension of principles and technologies used for<br />

whole-organ storage.<br />

Different media are available in the market for this application which were developed in many cases long before the<br />

explosion in cell therapy and tissue engineering. New media like HypoThermosol-FRS (BioLife) or Thermo-Gold (Revive)<br />

take the effects of cold shock damage (via stress pathways which are involved in necrosis and apoptosis) into account.<br />

Normally, cell or tissue function will be restored after 24 hours in culture at 37°C.<br />

Nevertheless, it is important to observe the post hypothermic storage viability for a week. Cells and tissues showing a high<br />

viability after warming can show a dramatic decrease after a few days. These effects depend on tissue or cell type.<br />
