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

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.
