A decellularized aortic homograft. Decellularization (also spelled decellularisation in British English) is the process used in biomedical engineering to isolate the extracellular matrix (ECM) of a tissue from its inhabiting cells, leaving an ECM scaffold of the original tissue, which can be used in artificial organ and tissue regeneration.
Acellular dermis is a type of biomaterial derived from processing human or animal tissues to remove cells and retain portions of the extracellular matrix (ECM). These materials are typically cell-free, distinguishing them from classical allografts and xenografts, can be integrated or incorporated into the body, and have been FDA approved for human use for more than 10 years in a wide range of ...
Split-thickness skin graft donor site eight days after removal of the skin. In order to remove the thin and well preserved skin slices and strips from the donor, surgeons use a special surgical instrument called a dermatome. This usually produces a split-thickness skin graft, which contains the epidermis with only a portion of the dermis.
The transplant is called an allograft, allogeneic transplant, or homograft. Most human tissue and organ transplants are allografts. It is contrasted with autotransplantation (from one part of the body to another in the same person), syngenic transplantation of isografts (grafts transplanted between two genetically identical individuals) and ...
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 ...
The dermal equivalent, also known as dermal replacement or neodermis, is an in vitro model of the dermal layer of skin. There is no specific way of forming a dermal equivalent, however the first dermal equivalent was constructed by seeding dermal fibroblasts into a collagen gel. This gel may then be allowed to contract as a model of wound ...
Buccal fat removal is permanent; the fat pads do not grow back. However, new techniques for restoring buccal fat such as injecting fat intra-orally back into the buccal space or applying a dermal fat graft are gaining popularity. Other options include mimicry with injectable fillers. [1] There is a lack of research on its long-term health ...
[3] [6] Cranial implants are placed and secured through surgical stabilisation using surgical wires, mini plates and screws to fill gaps in the bone of the skull, called the bone flap. [10] The conduct of alloplasty on the cranium restores lost or deficient use of the brain through the repair of mechanical defects, but is also able to provide ...
