This fully updated edition brings together a new set of protocols to arm epidermal cell biologists with tools and approaches to continue the quest to uncover the intricacies and regulatory mechanisms underlying epidermal cell development and function. The collection takes a detailed view at techniques currently being applied to this developing field. 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.

Comprehensive and cutting-edge, Epidermal Cells: Methods and Protocols, Fourth Edition serves as a valuable reference for experts as well as novices in the epidermal cell field.
