Stratum granulosum
The stratum granulosum (or granular layer) is a thin layer of cells in the
Keratinocytes migrating from the underlying stratum spinosum become known as granular cells in this layer. These cells contain keratohyalin
granules, which are filled with histidine- and cysteine-rich proteins that appear to bind the keratin filaments together.
Therefore, the main function of keratohyalin granules is to bind intermediate keratin filaments together.[2][3]
At the transition between this layer and the stratum corneum, cells secrete
organelles
