Question

The skin is protected by the action of cells that arise from bone marrow and migrate to the epidermis. Which cells serve this function?

Answer 1

Langerhan's cells

Step-by-step explanation:

The Langerhan's cells arise from the bone marrow and migrate to the epidermis. The Langerhan's cells are the body's first line of defense and play a significant role in antigen presentation. They need special stains to be visualized and are primarily found in the stratum spinosum. These are the mesenchymal origin obtained from CD34 positive stem cells of bone marrow and are part of the mononuclear phagocytic system.
