Concurrently, lamellar bodies release their lipid-rich contents, creating a waterproof barrier that marks the beginning of the cell death process. This layer is the sole site of active cell division, or mitosis, where keratinocyte stem cells proliferate and push older cells toward the surface.
Stratum Lucidum: The Hidden Layer in Thick Skin of Palms and Soles
This layer is absent in thin skin, highlighting the regional specialization within the epidermis. Stratum Corneum: The Ultimate Barrier Capping the epidermal layers is the stratum corneum, composed of 10 to 30 layers of anucleate, corneocytes.
These granules contain profilaggrin, which aggregates keratin filaments into larger, more stable bundles. Stratum Spinosum: The Prickle Layer As keratinocytes are pushed upward from the stratum basale, they enter the stratum spinosum, the thickest layer in most regions of the body.

The specific arrangement creates a resilient yet flexible barrier capable of constant renewal from the basal layer upward. Stratification and Cellular Organization The fundamental principle of epidermal histology is its stratified nature, composed of multiple layers of keratinocytes bound by desmosomes.
