Selection of raw materials for biomedical materials has been one of the focuses on development of biomaterials. In this study, we used porous silk fibroin scaffolds (PSFSs) prepared by freeze drying method and polyvinyl alcohol (PVA) sponges which have similar macro-structure such as average pore size and porosity. Both materials were implanted in femoral muscles of rats, and the biocompatibility...
The methods of dissolving Antheraea yamamai (A. yamamai) silk fibroin fibers and preparing the regenerated silk fibroin were studied. The molecular conformations of A. yamamai silk fibroin film treated by different concentration ethanol solution were investigated by XRD, FTIR, and Raman spectra. The results indicated that A. yamamai silk fibroin fibers could be completely dissolved in dense lithium...
Modification to surface texture of biomaterials, protein adsorption and interactions of biomaterials and cells have been studied in vitro for several decades in tissue engineering. However, few reports focus on the decoration of in vivo environment to implanted biomaterials and the effects of the decoration on cells proliferation and wound healing. In this study, we used porous silk fibroin materials...
