Spatially resolved multi-omics of human metabolic dysfunction-associated steatotic liver disease.

ABSTRACT: Metabolic dysfunction-associated steatotic liver disease (MASLD) is a leading cause of chronic liver disease worldwide. We generated single-cell and spatial transcriptomic and metabolomic maps from 61 human livers, including controls (n = 10), metabolic dysfunction-associated steatotic liver (MASL) (n = 17) and metabolic dysfunction-associated steatohepatitis (MASH) (n = 34). We identified microphthalmia-associated transcription factor (MITF) as a key regulator of the lipid-handling capacity of lipid-associated macrophages (LAMs), and further revealed a hepato-protective role of LAMs mediated through hepatocyte growth factor secretion. Unbiased deconvolution of spatial transcriptomics delineated a fibrosis-associated gene program enriched in advanced MASH, suggesting profibrotic crosstalk
