Mast Cell Population Density in Rat Skin.

Abstract
Summary Mast cell population counts were made in 8 normal rats of 10 skin regions. Counting was by the method of Floderus, which gives mast cell numbers per cubic millimeter of tissue. The results showed significant differences in the mast cell populations for various skin regions. Possible explanations of the population differences are discussed. The procedure for Floderus' counting method is given.
