Résumé

Sufficient numbers of pancreatic islets for successful allotransplantation can be achieved by storing and then pooling islets from several donors. Optimal MHC matching and infectious disease screening also require long-term storage of islets. Cryopreservation protocols may be optimized by modeling. The objective of the present work was to determine experimentally the biophysical parameters of canine islet cells: the osmotically inactive cell volume, hydraulic conductivity, cryoprotectant permeability coefficient and the reflection coefficient. A determination of these parameters allows the simulation of cell responses using computer models.
