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 ...
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 ...
In tissue engineering, physiological relevance means that living tissue constructs in vitro are morphologically and functionally similar to native tissue. [4] Bioengineering approaches to modify the mechanical properties of scaffolds and functionalize materials with growth factors or gene therapeutics. [5] [6]
The in vivo bioreactor is a tissue engineering paradigm that uses bioreactor methodology to grow neotissue in vivo that augments or replaces malfunctioning native tissue. . Tissue engineering principles are used to construct a confined, artificial bioreactor space in vivo that hosts a tissue scaffold and key biomolecules necessary for neotissue
The Journal of Tissue Engineering is a peer-reviewed open-access medical journal that covers research on tissue engineering. Its editors-in-chief are Hae-Won Kim (Dankook University) and Jonathan Knowles (UCL Eastman Dental Institute). It was established in 2010 and is published by SAGE Publications.
Cell engineering is the purposeful process of adding, deleting, or modifying genetic sequences in living cells to achieve biological engineering goals such as altering cell production, changing cell growth and proliferation requirements, adding or removing cell functions, and many more.
The first study on tissue engineering of heart valves was published in 1995. [11] During 1995 and 1996, Shinoka used a scaffold made of polyglycolic acid (PGA), approved by the FDA for human implantation, and seeded it with sheep endothelial cells and fibroblasts with the goal of replacing a sheep's pulmonary valve leaflet.

Partial-thickness tissue engineering uses one type of cell layer, this can be in monolayers or multilayers. Monolayer epithelial sheets suffice for the study of the basic biology of oral mucosa, for example its responses to stimuli such as mechanical stress, growth factor addition and radiation damage .
