Skin section. Coloured transmission electron micrograph (TEM) of a section through skin of the ear. Keratinocytes or skin cells (pink and brown) are found in the epidermal layer of the skin. The cells have a large nucleus (orange), which contains their genetic information. The cells' cytoplasm is rich in filaments of the protein cytokeratin. The filaments extend into junctions between the cells known as desmosomes, which help the cells to withstand mechanical stress. Dermis (yellow) consisting mainly of collagen fibres underlies the epidermis. Magnification: x3000 when printed at 10 centimetres high. | |
