Fibrin scaffold is an important element in tissue engineering approaches as a scaffold material. It is advantageous opposed to synthetic polymers and collagen gels when cost, inflammation , immune response , toxicity and cell adhesion are concerned. [ 11 ]
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 ...
An example of a naturally dissolving stent is the 'Absorb' stent 'produced by Abbott [25] that has several design components and features: base scaffold: a poly(L-lactide) polymer similar to that in dissolvable stitches is shaped into a tube made up of zigzag hoops linked together by bridges; drug-eluting layer': a mixture of poly-D, L-lactide ...
Scaffolds localize the signaling reaction to a specific area in the cell, a process that could be important for the local production of signaling intermediates. A particular example of this process is the scaffold, A-kinase anchor proteins (AKAPs), which target cyclic AMP-dependent protein kinase to various sites in the cell. [7]
In computational biology, N50 and L50 are statistics of a set of contig or scaffold lengths. The N50 is similar to a mean or median of lengths, but has greater weight given to the longer contigs. It is used widely in genome assembly, especially in reference to contig lengths within a draft assembly.
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. [3]
A hip implant is an example of an application of biomaterials. A biomaterial is a substance that has been engineered to interact with biological systems for a medical purpose – either a therapeutic (treat, augment, repair, or replace a tissue function of the body) or a diagnostic one.
Biomedical engineering and bioinstrumentation are new terms, but the practice behind them has existed for many generations. Since the beginning of mankind, humans have used what was available to them to treat the medical mishaps they encountered. Biomedical engineering was most developed in the nineteenth century.
