This detailed book delves into the diverse techniques and applications to target, isolate, image, phenotype, and analyze tissue-resident and monocyte-derived macrophages. The contents aim to describe the current knowledge about macrophage development and function which forces the scientific field to move beyond the previously described M1/M2 macrophage paradigm to be able to dissect macrophage functions within their specific niches during health and disease. Written for the highly successful Methods in Molecular Biology series, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step and readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls. Thorough and practical, Tissue-Resident Macrophages: Methods and Protocols provides scientists entering the macrophage field with information and tools that allow them to dive into the state-of-the-art methodology used in this vital field.
