This detailed volume explores techniques for researching brown adipose tissue (BAT) and the fascinating biology and therapeutic potential of thermogenic adipocytes. The content reflects the advancing technologies in genetics, imaging, and 'omics strategies that are allowing researchers to probe BAT biology at unprecedented depths and detail, yet it also presents classic physiology principles, which remain the core tenets of BAT biology. 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, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls.
