Morphology of hair in normal and mutant laboratory mice

Inbred laboratory mice are mammals and therefore are haired. Mice develop m any of the same diseases as humans and have become the premier in vivo mode l for studying biology, pathology, genetics, and molecular mechanisms. Mice are useful tools to study hair biology, Examples of characterized mutant m ice with abnormal pilosebaceous unit phenotypes are presented to illustrate the value of these animals as models to help understand human diseases of the skin and hair.
