Abstract
A protocol for generating human liver organoids (HLOs) from induced pluripotent stem cells and inducing metabolic-associated steatohepatitis (MASH) features through oleic acid and TGFβ treatment. The M-HLO model demonstrates lipid accumulation, oxidative stress, mitochondrial dysfunction, inflammation, and fibrosis, enabling MASH pathogenesis study and drug screening.
