Cultured MDCK en:wikipedia:epithelial cells were stained for en:wikipedia:keratin, desmoplakin, and en:wikipedia:DNA. The stained cells were visualized by scanning laser confocal microscopy. The image shows how keratin cytoskeletal filaments are concentrated around the edge of the cells and merge into the desmoplakin which is located at en:wikipedia:desmosomes of the surface membrane. The network of keratin to desmosome to keratin linking the cells of an epithelial sheet is what holds together tissues like skin.
