Patent number: 10683486Abstract: Methods for producing hepatocytes from pluripotent human stem cells are disclosed herein. The stem cells are plated on a cell culture substrate comprising two laminins. The stem cells are then exposed to different cell culture mediums to induce differentiation. The resulting hepatocytes have higher metabolic capacity compared to hepatocytes cultured on different substrates.Type: GrantFiled: October 29, 2016Date of Patent: June 16, 2020Assignees: BIOLAMINA AB, THE UNIVERSITY OF EDINBURGHInventors: Louise Kristina Hagbard, Carl Gunnar Jesper Ericsson, Katherine Rachel Cameron, David Colin Hay, Stuart John Forbes, Hassan Rashidi
