This extensive book brings together leading melanoma researchers from across the world and highlights many of the cutting-edge protocols and experimental systems currently being used to investigate questions surrounding this disease. The volume opens with sections on 2D and 3D cell culture-based approaches for studying melanoma biology, and continues with collections of chapters examining various approaches for detecting, isolating, and characterizing circulating melanoma cells, circulating tumor DNA, and exosomes, as well as experimental procedures for studying and detecting melanoma metastasis in both pre-clinical and clinical settings, bioinformatics-based approaches, protocols for quantifying and characterizing immune cell infiltrates in both melanoma tumors and tertiary lymphoid structures, and development and evaluation of therapeutic strategies for melanoma treatment. 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.
