To the left, which are the deeper layers of the epithelium in this image, is the continuation of the stratum spinosum. The two to six layers of cells that contain darkly basophilic granules make up the stratum granulosum. The granules in these cells are keratohyalin granules. The brightly acidophilic material to the right that layer is made up of keratinized (cornified) squamous epithelial cells and is known as the stratum corneum. Often, the stratum corneum loses at least half of its original thickness during processing.
