Why a skin graft?
a Skin Graft is a type of medical grafting involving the transplantation of skin. The transplanted tissue is called a skin graft. Skin Grafting is often used to treat: -Extensive wounding or trauma -Burns -Areas of extensive skin loss due to infection such as necrotizing fasciitis or purpura fulminans -Specific surgeries that may require skin grafts for healing to occur. Skin Grafts are often employed after serious injuries when some of the bodys skin is damaged. Surgical removal of the damaged skin is followed by skin grafting. There are 2 types of skin grafts: the more common type is where a thin layer is removed from a healthy part of the body like peeling a potato, OR a full thickness skin graft, which involves pitching and cutting skin away from donor section. A full thickness graft is more risky, in terms of the body accepting the skin, yet it leaves only a scar line on the donor section, similar to a Ceasarean section scar.

What is the function of the stratum germinativum?
This is the deepest layer of the skin structure and, as such, acts as stem cells since they are the least differentiated or least specific type of skin cell. As they migrate upward, environmental factors and neighboring cells increasingly cause them to become more specific cell types. Ocassionally called the "basement membrane," found to be essential for proper healing after thermal injuries to the skin. Was eventually found to be the reason why earlier attempts at skin grafts using only upper skin cells were found not to be effective in 3-rd degree full thickness burns. Modern skin grafts now use a layer of these stratum g. cells on the artificial skin, followed by other cells added later. The result has been a marked improvement in the rate of successful skin grafts.
