This volume contains a comprehensive collection of laboratory protocols used by researchers to analyze varied aspects of non-alcoholic steatohepatitis (NASH). The chapters in this book cover topics such as methods for histological diagnosis of NASH; the purpose of generating an in vivo NASH model; protocols for isolating hepatocytes and Kupffer cells, bone marrow derived macrophages, and adipocytes; techniques to develop human pluripotent stem cells-derived liver organoids; single-cell and RNA-sequencing; and a description of how to extract exosomes and exosomal miRNAs from mesenchymal stem cells. Written in the highly successful Methods in Molecular Biology series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls.
