More on Enhancing Healing

If you understand the biomolecular processes of healing, then you can step in to improve them. Many research teams around the world are doing just this. One such effect is examined here by Science: "Even on a cellular level, wound healing takes time. The body must target a large number of molecules called growth factors to just the right area to help repair the damage. ... The new tools are molecules called peptide amphiphiles. Once injected into the body, the amphiphiles self-assemble into long, thin nanofibers, which hang out in the wound area. ... in those given the amphiphiles, nanofibers assembled at the injury site and stayed put, drawing the body's own growth factors to the injury site. A month later, the team found that the hearts of the animals that received the amphiphiles pumped blood nearly as well as those of healthy animals. In contrast, the hearts of the control animals contracted about 50% less than normal. The same nanofibers also dramatically hastened wound healing in rabbits."
