WebThe granule cell layer (stratum granulosum) is the next layer (3-5 layers of cells). As the cells move up into this layer, they start to lose their nuclei and cytoplasmic organelles, and turn into the keratinised squames of the next layer. The granules contain a lipid rich secretion, which acts as a water sealant.
