Micro-mass cultures of C3H-10T1/2 cells at varied oxygen tensions stained with Alcian blue. A commonly applied definition of tissue engineering, as stated by Langer [3] and Vacanti, [4] is "an interdisciplinary field that applies the principles of engineering and life sciences toward the development of biological substitutes that restore, maintain, or improve [Biological tissue] function or a ...
Artificial skin made by Integra composed of an outer silicone film and inner matrix of cross linked fibers. Artificial skin is a collagen scaffold that induces regeneration of skin in mammals such as humans. The term was used in the late 1970s and early 1980s to describe a new treatment for massive burns.
A major technology of regenerative medicine is tissue engineering, [2] which has variously been defined as "an interdisciplinary field that applies the principles of engineering and the life sciences toward the development of biological substitutes that restore, maintain, or improve tissue function", or "the creation of new tissue by the ...
Tissue expansion is a technique used by plastic, maxillofacial and reconstructive surgeons to cause the body to grow additional skin, bone, or other tissues. Other biological phenomena such as tissue inflammation can also be considered expansion (see tissue inflammation below).
Vacanti claimed that February to have replicated the effect in human skin fibroblast cells, [24] and said "We believe that this is exactly what happens in the body during attempts to repair any damaged or diseased tissue". [25] Vacanti said in 2012 he had used the technique to grow a replacement trachea using autologous cells from a patient. [23]
AlloDerm is the first type of acellular dermal matrix (ADM) derived from the skin of cadavers from the collagen fiber network after the removal of the epidermal layer of the cadaveric skin. [ 13 ] [ 14 ] It is widely used in dental surgeries for gingival grafting , [ 15 ] abdominal hernia repair, [ 13 ] oculoplastic and orbital surgeries, [ 14 ...
Dermal fibroblasts are cells within the dermis layer of skin which are responsible for generating connective tissue and allowing the skin to recover from injury. [1] Using organelles (particularly the rough endoplasmic reticulum), dermal fibroblasts generate and maintain the connective tissue which unites separate cell layers. [2]
The electrospun scaffolds made for tissue engineering applications can be penetrated with cells to treat or replace biological targets. [65] Nanofibrous wound dressings [66] have excellent capability to isolate the wound from microbial infections. [67] [68] Other medical textile materials such as sutures are also attainable via electrospinning ...
