Successful cryopreservation of auricle fragments from rat hearts at -196 degrees C. 1978

G Matthes, and H A Hackensellner, and A Hartwig

The influence of electrolyte composition and glucose concentration of a cryoprotective medium on the survival of auricle fragments from adult rat hearts after storage at -196 degrees C was investigated. Using a K+-, Mg++-, Ca++-rich solution with increased glucose concentration, a high rate of surviving fragments was found after cryopreservation.

D005947	Glucose	A primary source of energy for living organisms. It is naturally occurring and is found in fruits and other parts of plants in its free state. It is used therapeutically in fluid and nutrient replacement.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D014021	Tissue Preservation	The process by which a tissue or aggregate of cells is kept alive outside of the organism from which it was derived (i.e., kept from decay by means of a chemical agent, cooling, or a fluid substitute that mimics the natural state within the organism).
