A novel technology using tiny “nanofibers” shows promise for helping the body repair and restore tissue damaged through injury or disease, including brain trauma, according to new research (Ellis-Behnke RG et al. Proc Natl Acad Sci U S A. 2006;103:5054-5059). The same material applied to a wound may also help surgeons stanch bleeding within seconds.
The nanoscale fibers are composed of peptides that self-assemble into a fibrous mesh that mimics the natural connective tissue of the body's extracellular matrix. “The peptide nanofiber scaffold not only represents a previously undiscovered nanobiomedical technology for tissue repair and restoration but also raises the possibility of effective treatment of [central nervous system] and other tissue or organ trauma,” the researchers noted.
