Stratum granulosum
Stratum granulosal cells contain keratohyalin granules of varying sizes. These electron dense, non-membrane-enclosed structures associate with tonofibrils and enlarge by fusing with adjacent granules. Lamellar bodies, formed in the upper layers of stratum spinosum and released into the intercellular space, contain a sealant that contributes to the water barrier of the skin. 10,000x
