Abstract
This protocol describes the establishment and culture of patient-derived hepatoblastoma tumoroids in three-dimensional Matrigel-based systems. The tumoroids are propagated in defined media containing specific growth factors (EGF, FGF10, HGF) to generate functional 3D tumor models that recapitulate primary tumor heterogeneity, including differential expression of Wnt pathway components, biliary lineage markers (SOX4, KRT19), and FGF19 expression patterns. These systems enable functional studies of growth factor dependencies and signaling pathway requirements.
