This volume delivers the most important laboratory techniques that underlie dermatological investigation, including in situ, in vitro, ex vivo, and in vivo models of skin, its appendages (hair follicles, sebaceous and sweat glands), and immune cells. Also included are unique techniques that unravel epigenetic mechanisms in skin and hair follicle cells, such as gene organization in the nucleus and gene expression regulation by the non-coding transcriptome, which are important recent developments in investigative dermatology. 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. Authoritative and practical, Molecular Dermatology: Methods and Protocols serves as an essential resource for researchers working in the areas of fundamental as well as applied dermatological science.
