Epidermis,fluorescent light micrograph. The epidermis is the outermost layer of the skin. Keratin (green,top left) forms the top layer of the epidermis and acts as a barrier between the body and the outside world. Defensin (red) is produced by keratinocytes (keratin-producing cells,blue) and acts as a natural antimicrobial. An artery (green/blue) can be seen running through the epidermis at bottom right | |
