Adult Thin Skin Histology - Epidermis

This image focusses on the epidermis (epithelial) layer of the thin skin. (Stain - Haematoxylin Eosin)

• stratum corneum - the most superficial part of the epidermis. Nuclei are not visible in this layer.
• Cell outlines may be visible at high magnification or, in the form of artefacts, as cracks or clefts in the stratum corneum.
• stratum granulosum - is formed by a single layer of very dark and flattened cells in thin skin.
  • Several layers of cells containing keratohyalin granules are visible in thick skin.
• stratum spinosum - polyhedral cells with clear outlines.
• stratum basale is formed by a single layer of cuboidal or columnar cells and delimits the epidermis from the dermis. This layer contains the keratinocyte stem cell population required for the continual replacement of cells as they differentiate and are shed from the skin (squams).
