Improvement of hepatocyte recovery from rat liver subjected to 1-hour warm ischemic injury by using citrate phosphate dextrose added to euro-collins perfusion solution

Isolation of GMP Grade Human Hepatocytes from Remnant Liver Tissue of Living Donor Liver Transplantation

For the purpose of clinical research of hepatocyte transplantation, procedures for isolation, cryopreservation, thawing, and functional assessment of hepatocytes are described. Although demands for human hepatocytes are increasing in not only cell therapy but also drug development, it is highly difficult to obtain good lots of hepatocytes from human liver tissue. This chapter describes essential issues such as alleviation of warm ischemia, prevention of shear stress, optimization of cryopreservation, and functional assessment, along with securement of quality. All procedures described here are compliant with good manufacturing procedure (GMP) in cell processing facility, approved by the act on measures to ensure safety of regenerative medicine and ethical regulations in Japan.
