Artificial Skin By: Raymond Litteaur

History of Burns  Before artificial skin was developed, burns covering 50% of the body were considered to be fatal.  In 2000, artificial skin cut death rates in people with over 70% burns from 100% to 40%.  Skin is the body’s largest organs and protects us from physical damage, disease, and controls our body’s temperature.

How Artificial Skin is Made  Skin is usually donated by other donors.  Fibroblasts are removed from the donated skin and are frozen until they are needed.  The fibroblasts are placed on a polymeric mesh scaffolding, gather oxygen, and grow new cells.  The cells are then transferred to a culture system.

Artificial Skin cont.  After 4 weeks the polymer mesh dissolves and leaves behind a new layer of dermal skin.  When the growth cycle is completed, they add more nutrients.  Keratinocytes are added to the collagen and are exposed to air to form epidermal layers.  The skin is now completed and is stored in sterile contains until ready to use.

How Artificial Skin is Used  Artificial skin is already being used for burn victims and soon will be available for other skin disorders.  The skin is not used for a permanent replacement, but to temporary cover the skin until your skin can grow back naturally.

The Future  Because skin is an organ, there are many similarities between skin and other organs.  There is hope to regenerate joints, ears, noses, livers, kidneys, and hearts.
