In microscopic views of skin, the stratum granulosum layer of the epidermis lies between the stratum spinosum below and the stratum lucidum above.
This layer typically contains 1 to 3 rows of flattend cells with many small basophilic granules in their cytoplasm.
These keratohyalin granules are a step in the synthesis of the waterproofing protein keratin, and contain large amounts of filaggrin.
This is the highest layer in the epidermis where living cells are found, the stratum lucidum above appears clear due to auto-digestion of cellular organelles.
This layer also includes lamellar granules and tonofibrils.
