Biomineralization of Engineered Spider Silk

چکیده
Materials based on biodegradable polyesters such as poly(butylene terephthalate) (PBT) 20 or poly(butylene terephthalate-co-poly(alkylene glycol) terephthalate) (PBTAT) have potential 21 application as pro-regenerative scaffolds for bone tissue engineering. Herein is reported the 22 preparation of films composed of PBT or PBTAT and an engineered spider silk protein, 23 (eADF4(C16)), that displays multiple carboxylic acid moieties capable of binding calcium ions and 24 facilitating their biomineralization with calcium carbonate or calcium phosphate. Human 25 mesenchymal stem cells cultured on films mineralized with calcium phosphate show enhanced 26 levels of alkaline phosphatase activity suggesting that such composites have potential use for bone 27 tissue engineering. 28

متن کاملSilkworms transformed with chimeric silkworm/spider silk genes spin composite silk fibers with improved mechanical properties.
The development of a spider silk-manufacturing process is of great interest. However, there are serious problems with natural manufacturing through spider farming, and standard recombinant protein production platforms have provided limited progress due to their inability to assemble spider silk proteins into fibers. Thus, we used piggyBac vectors to create transgenic silkworms encoding chimeric...
متن کاملSynthetic biology increases efficiency of Escherichia coli to produce Parawixia bistriata spider silk protein
Background Spider dragline silk is considered to be the toughest biopolymer on Earth due to an extraordinary combination of strength and elasticity. With synthetic biology it is possible to express recombinant spider silk proteins, which are characterized by a highly repetitive rich glycine and alanine sequence [1]. However, production of high molecular weight spider silk protein can be difficu...
متن کاملInterfacial rheological properties of recombinant spider-silk proteins.
Freestanding protein films are interesting for many applications ranging from microencapsulation to tissue engineering. Here, the authors use interfacial rheology to characterize the adsorption kinetics and the rheology of spider-silk films formed at an oil water interface. The high surface activity of the engineered spider-silk proteins results in a fast formation of highly stable films, which...
متن کاملEngineered spider silk protein-based composites for drug delivery.
Silk protein-based materials are promising materials for the delivery of drugs and other active ingredients, due to their processability, biocompatibility, and biodegradability. The preparation of films composed of an engineered spider silk protein (eADF4(C16)) in combination with either a polyester (polycaprolactone) or a polyurethane (pellethane), and their physical properties are described. ...
