Abstract

Here, we present a detailed protocol for the identification of potential oncofetal targets for hepatocellular carcinoma (HCC) patients through a hepatocyte differentiation model and a sorafenib refractory cell-line-derived xenograft model. We describe the procedures of tumor sphere formation, organoid generation, and subcutaneous tumor formation for functional studies. We then detail the procedures of immunohistochemistry and immunofluorescence for examination of changes in lineage-specific markers. Finally, we describe the development of antibody-based therapeutics targeting tumor lineage plasticity in HCC. For complete details on the use and execution of this protocol, please refer to Kong et al. (2021).¹.
