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 ...
Physiological relevance is a critical factor in biomedical research because it helps to bridge the gap between basic science and clinical application. Researchers aim to design studies that not only yield statistically significant results but also have direct implications for understanding human health and disease. [ 1 ]
Fibrin scaffold use is helpful in repairing injuries to the urinary tract, [3] liver [4] lung, [5] spleen, [6] kidney, [7] and heart. [8] In biomedical research, fibrin scaffolds have been used to fill bone cavities, repair neurons, heart valves, [9] vascular grafts [10] and the surface of the eye.
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.
A common example of how scaffolds enhance specificity is a scaffold that binds a protein kinase and its substrate, thereby ensuring specific kinase phosphorylation. Additionally, some signaling proteins require multiple interactions for activation and scaffold tethering may be able to convert these interactions into one interaction that results ...
Nano-scaffolding or nanoscaffolding is a medical process used to regrow tissue and bone, including limbs and organs. The nano-scaffold is a three-dimensional structure composed of polymer fibers very small that are scaled from a Nanometer (10 −9 m) scale. [1]
Biomimetic materials in tissue engineering are materials that have been designed such that they elicit specified cellular responses mediated by interactions with scaffold-tethered peptides from extracellular matrix (ECM) proteins; essentially, the incorporation of cell-binding peptides into biomaterials via chemical or physical modification.

Cells can orient in response to contact guidance when located inside three-dimensional structures, such as collagen gels, scaffolds, and soft tissues. In those conditions, the geometrical cues provided by collagen or scaffold fibers are able to influence the orientation of cells.
