Wikipedia definition
2. Stratum granulosumThe stratum granulosum (or granular layer) is a thin layer of cells in the epidermis. Keratinocytes migrating from the underlying stratum spinosum become known as granular cells in this layer. These cells contain keratohyalin granules, protein structures that promote hydration and crosslinking of keratin. At the transition between this layer and the stratum corneum, cells secrete lamellar bodies into the extracellular space.
