title: The hairless mouse ear for in vivo studies of skin microcirculation.
abstract: The homozygous (hr/hr) hairless mouse ear was introduced in 1980 by Eriksson and coworkers as a model for in vivo studies of the skin microcirculation. Herein we expand on this work, presenting results of in vivo microvascular parameter measurements and morphologic studies in the intact ear. The in vivo measurements include microvascular diameter, RBC velocity, capillary density, and the frequency and amplitude of arteriolar vasomotion. In connection with the in vivo studies, a detailed anatomic description of the overall and vascular anatomy is given. Additionally, the preparation techniques for carrying out these in vivo and morphologic studies in the mouse ear are presented in detail.
