摘要: An artificial liver support system is described herein which comprises cryopreserved hepatocytes having an initial viability of 80-99%. Further disclosed are hepatocytes cryopreserved by dispensing hepatocytes into freezing containers, freezing the containers from between minus 50 to minus 90 degrees Celsius, storing the containers in liquid or vapor nitrogen, thawing the cryopreserved hepatocytes when ready for use and removing residual cryoprotectant media.

摘要: The invention is based in part on the observation that significant portions of porcine livers appear to remain intact after perfusion by standard methods, suggesting that the perfusion procedures employed do not result in complete enzymatic digestion. Recovery of cells is therefore substantially lower than would be possible if the organs were thoroughly digested. It is found that increased perfusion flow rate, occlusion of at least one major blood vessel leading out of the organ, increased enzymatic digestion time, and vigorous tissue dissociation techniques can be combined to afford a uniquely high yield of viable cells.

摘要: An artifical pancreatic perfusion device comprising a hollow fiber having a porosity ranging from about 25 Kd to about 200 Kd. The hollow fiber has one end connected to a blood vessel for receiving blood and a second end connected to a blood vessel for returning said blood. Islets of Langerhans surround the hollow fiber. The hollow fiber and islets are surrounded by a housing comprising a semipermeable membrane having a pore size small enough to offer protection to the islets and host from immune reactive substances. Further disclosed is a method for providing and regulating insulin to insulin deficient individuals.
