3D Spheroid Model: A Methodological Approach for Advancing Cancer and Immunology Research

Three-dimensional (3D) spheroid cultures are revolutionizing immunology and cancer research by offering physiologically relevant models that mimic the complexity of in vivo tissues. Unlike traditional two-dimensional (2D) cultures, 3D spheroids recapitulate the architecture, cell-cell interactions, and microenvironmental conditions of native tissues. Therefore, these 3D systems bridge the gap between simple 2D culture methods and complex animal models by providing an intermediate that balances control with biological relevance. This chapter explores the use of 3D spheroids in understanding immune dynamics and developing therapeutic strategies for cancer.
