All about Skin Cell (Keratinocyte)
|Description||Skin cells are the outermost layer of protection for the body. The skin protects against pathogens and excessive water loss. It maintains a constant temperature by sweating when necessary, and it has nerve endings for sensing touch. This is a nice gift for a dermatologist, teacher, or anybody interested in anatomy!|
|Name||Keratinocytes get their name because they produce the protein Keratin, and –cyte is the ending indicating that it is a “cell.” The same construction is true for Melanocytes, which make melanin. Merkel cells and Langerhans cells are named after the scientists that discovered them.
Keratinocytes: are the skin cells on the outermost layer, the ones that we see. They produce keratin, a protein that helps to strengthen the barrier.
Melanocytes: produce melanin, the pigment of the skin.
Merkel Cells: help you sense touch.
Langerhans Cells: work to protect the body against pathogens. To help the immune system, they bind to antigens that try to come through the skin.
|Actual Size||30 microns, comparable to the diameter of the finest pieces of human hair.|
|System||Integumentary System: protects the body from damage.|
|History||1868: Paul Langerhans was the first to describe Langerhans cells. Only later was their immune role recognized.
1875: Friedrich Sigmund Merkel, a German scientist, was the first to describe touch cells, later named Merkel cells, in the skin of vertebrates.
|Fascinating Facts||Dead Skin: You shed between 30,000-40,000 skin cells every minute!
Self-Renewal: Skin renews itself once every 35 days.
