In addition, biomedical materials have claimed attention because of the increased interest in tissue engineering materials for wound care and regenerative medicine. Moreover, the nanostructure and morphological similarities with collagen make BC attractive for cell immobilization, cell support and Natural Extracellular Matrix (ECM) Scaffolds. In this work, we present the extracellular matrix (ECM) using the bacterial cellulose (Nanoskin<sup>®</sup>) which regulates cell behavior by influencing cell proliferation, survival, shape, migration and differentiation. Bacterial cellulose fermentation process is modified before the bacteria are inoculated for mimicking ECM to cells support and built new local material for wound healing. Chemical groups influences and thermal behavior in bacterial cellulose were analyzed using transmission infrared spectroscopy (FTIR) and thermogravimetric analysis (TGA), respectively. Besides, In vivo analysis was evaluated with clinical study at Sharjah Kuwait Hospital.展开更多

In addition, it has called attention for uses such as membrane for wound care and tissue engineering. In this work, the bacterial cellulose fermentation process is modified by the addition of natural materials before the bacteria are inoculated. In vivo behavior using natural ECM for regenerative medicine is presented and completed wound healing process is 3 months.展开更多
