Distribution of Langerhans cells in Swiss Webster mouse skin.

The pattern of surface density and distribution of Langerhans Cells (LC) in the Swiss Webster (SW) albino mouse is reported. LC were demonstrated using ATP-Pb and their densities evaluated in the skin of anterior and posterior foot-pads, tail, abdomen, back and ear. Cells were counted using a light microscope with a drawing tube by projecting 0.01 mm2 areas at 150X magnification. The distribution and density of LC were quite different in the various regions of SW mouse skin.
