Dynamic perifusion to maintain and assess isolated pancreatic islets.
Advances in human islet transplant techniques are hampered by the inability to assess the quality of isolated islets. A flow culture system was developed to perifuse isolated pancreatic islets or cultured beta-cell lines in order to continuously and noninvasively assess cell function and viability with high kinetic resolution. Continuous perifusion of large amounts of islet tissue as isolated from
