Development of a Three-Dimensional Multicellular Model of Human Neuroblastoma Using Matrigel as an Extracellular Matrix Analogue.

Neuroblastoma, the most prevalent extracranial solid tumor in children, poses therapeutic challenges due to its variable clinical course and propensity for metastasis. Despite advances in treatment strategies like chemotherapy, drug resistance remains a significant concern, highlighting the need for improved models to study tumor behavior and drug responses. This chapter proposes the development of a three-dimensional multicellular model of human neuroblastoma using Matrigel as an ECM analogue. Such models aim to replicate the complexity of the tumor microenvironment, providing valuable insights into tumor progression and drug resistance mechanisms. By recapitulating key features of neuroblastoma within a physiologically relevant context, these models offer a platform for preclinical drug screening and therapeutic development.
