SEM of section through human skin
Skin. Coloured scanning electron micrograph of a section through the human skin. The uppermost layers of the skin (pink and red) make up the epidermis. The surface of the epidermis (at top, pink) is the cornified layer composed of flattened, fused keratin-rich cell remnants. The dead cells from this layer are continuously being shed and replaced from cells from the living epidermal layers below (red). These layers contain keratinocytes, specialized cells that synthesize keratin. The lowest layer shown here is the dermis (yellow). The dermis is a thick layer of fibrous connective tissue which supports and nourishes the epidermis. Magnification: unknown

EDITORS COMMENTS
This print offers a mesmerizing glimpse into the intricate structure of human skin. Through the lens of a scanning electron microscope, we are presented with an extraordinary view of the various layers that compose this vital organ. The vibrant colors in this image highlight the uppermost layers known as the epidermis. The pink and red hues represent different regions within this layer. At the top, we can observe the cornified layer, which forms a protective barrier on our skin's surface. Composed of flattened and fused keratin-rich cell remnants, it shields us from external elements. Interestingly, this cornified layer is continuously shedding dead cells while simultaneously replenishing itself with new ones from below. These living epidermal layers (depicted in red) contain specialized cells called keratinocytes that synthesize keratin - a protein crucial for maintaining skin strength and elasticity. Beneath these remarkable epidermal layers lies the dermis, showcased here in yellow tones. This thick layer consists of fibrous connective tissue responsible for supporting and nourishing the overlying epidermis. With its unknown magnification level, this photograph invites us to marvel at nature's intricacy on a microscopic scale. It serves as a reminder of how our bodies are composed of awe-inspiring structures working harmoniously to protect and sustain us.
