Application of far-infrared spectroscopy to the structural identification of protein materials

, 2018
Far-IR spectroscopy was applied to monitor the structure of two types of silk fibroins and the results indicate that they both show several sharp characteristic peaks, which are totally different from those of globular proteins.

Engineering Approaches to Modify Immunomodulatory Functions of Mesenchymal Stromal Cells (MSCs): Tissue Regeneration and Clinical Application

Advanced Science, EarlyView.
Mesenchymal stromal cells (MSCs) show promise for treating immune‐related disorders through immunomodulation and tissue regeneration. This review gives a brief overview of current clinical approval of MSC therapies. It also discussed how bioengineering, including genetic modification, biomaterial delivery, extracellular vesicles, and iPSC‐derived MSCs,

Reaction of Silk Fibroin with Diazomethane

Textile Research, 1940
The reactive groups in silk are intimately related to the absorp tion of moisture, acids, alkalies, or dyes, and to physical properties such as extensibility and tensile strength. A large proportion of these gorups are present in silk fibroin in the form of hydroxyl groups of the amino acid tyrosine.

Macroporous Silk Fibroin Cryogels

Biomacromolecules, 2013
Silk fibroin cryogels with remarkable properties were obtained from frozen fibroin solutions (4.2-12.6%) at subzero temperatures between -5 and -22 °C. This was achieved by the addition of ethylene glycol diglycidyl ether (EGDE) into the cryogelation system.

Relative abundance of proteins from functional categories in five cocoon layers.

, 2015
Molar abundance of proteins was estimated with iBAQ intensities (A). Molar abundances of fibroins (B), sericins (C) and seroins (D) were compared among five cocoon layers by LFQ intensities.

Silk fibroin scaffolds with muscle-like elasticity support in vitro differentiation of human skeletal muscle cells [PDF]

, 2016
Human adult skeletal muscle has a limited ability to regenerate after injury and therapeutic options for volumetric muscle loss are few. Technologies to enhance regeneration of tissues generally rely upon bioscaffolds to mimic aspects of the tissue ...

The crystal structure of silk fibroin [PDF]

Acta Crystallographica, 1954
An X-ray investigation of a precipitate obtained by the action of pancreatic enzymes on an aqueous solution of silk fibroin suggests that the precipitate has essentially the same crystal structure as the silk fibre. Since the precipitate consists almost entirely of glycine, alanine and serine residues, it is concluded that only one crystalline phase ...
