Primary human hepatocytes from metabolic-disordered children recreate highly differentiated liver-tissue-like spheroids on alginate scaffolds Academic Article uri icon


  • Human hepatocyte transplantation has not been routinely established as an alternative to liver transplantation in liver disease due to low cell engraftment rates. Preimplantation in vitro engineering of liver tissue using primary human hepatocytes on three-dimensional scaffolds could be an alternative model. Alginate bioscaffolds were seeded with 1×106 hepatocytes freshly isolated from the livers of three children suffering from different metabolic disorders. During a culture period of 14 days only a marginal loss of hepatocytes was observed via measurement of DNA content per scaffold. Formation of hepatocyte spheroids was detected from day 3 onward using transmission light microscopy. Biochemical assays for albumin, α1-antitrypsin, and urea revealed excellent metabolic function with its maximum at day 7. Low lactate dehydrogenase enzyme release demonstrated minor cellular membrane damage. Hematoxylin and eosin and periodic acid Schiff staining displayed high cell viability and well-preserved glycogen sto...
