What is bioengineered skin?
Bioengineered skin consists of an outer epidermal layer and/or a dermal layer (the layer of skin between the epidermis and the subcutaneous tissue) embedded into an acellular matrix (a support structure) forming a biological skin substitute.
What is a skin substitute definition?
DEFINITION. Skin substitutes are heterogeneous group of wound coverage materials that aid in would closure and replace the functions of the skin, either temporarily or permanently, depending on the product characteristics.
What is synthetic tissue substitute?
Commonly used synthetic acellular skin substitutes are Biobrane®, Integra®, Alloderm™, and TransCyte™. The natural skin substitutes, commonly called tissue engineered skin, are mainly cultured allogenic or autologous cell suspensions or sheets, which are used on their own or along with a dermal matrix.
What is bioengineered skin substitutes?
The bioengineered skin substitutes used at UPMC Wound Healing Services closely resemble human skin in structure and function, and they can be used temporarily or permanently. In wound healing, skin substitutes can be used for patients with: Venous leg wounds. Burns. Diabetic foot wounds.
What is acellular skin substitutes?
The Alloderm® skin substitute is essentially formed from acellular matrix derived from a cadaveric dermis. The allodermis is processed by salt to remove the epidermis and then extracted with a solution to remove any cellular material.
What is skin substitute made of?
Cellular allogenic skin substitutes The Transcyte® tissue engineered skin substitute is made from a nylon mesh and a silastic semi permissible and biocompatible layer.
How do skin substitutes work?
Skin substitutes are engineered dressings designed to facilitate wound closure by performing as many of the key roles of normal skin as possible. They lack dermal appendages, an intact microvascular network, immune cells or melanocytes.
How is synthetic skin made?
Artificial skin is produced by bioengineering different types of skin cells. Some are made using a patient’s own skin cells, tissue from donated cadavers, animal tissue cells, or a combination of these. How they work is dependent on the skin function they are attempting to replace.
What is synthetic skin graft?
They are made of both layers of the skin (dermal and epidermal), ideally mimicking natural tissue. Artificial dermo-epidermal grafts are often prepared by culture of keratinocytes on the surface of the dermal layer with or without fibroblasts incorporated.
What is artificial skin used for?
The primary current application of artificial skin is for the treatment of skin loss or damage on burn patients. Alternatively however, artificial skin is now being used in some places to treat patients with skin diseases, such as diabetic foot ulcers, and severe scarring [1].
What are desired mechanical properties of a skin substitute?
Methods: Desirable traits of an ideal skin substitute include adherence, moisture permeability control, infection control, safety, pain management, physical adaptability, transparency, stability, cost-effectiveness, and ease of application and removal.
What is skin autograft?
Skin transplant; Skin autografting; FTSG; STSG; Split thickness skin graft; Full thickness skin graft. A skin graft is a patch of skin that is removed by surgery from one area of the body and transplanted, or attached, to another area. The skin is the largest organ of the body.

What is the other name of artificial skin?
Several types of human skin recombinants, also called artificial skin, that provide this critical 3-D structure, have now been reconstructed in vitro. This review contemplates the use of these organotypic skin models in different applications, including substitutes to animal testing.
