The BBC reports on another way to potentially guide cells in your body to take that extra step to repair damage: ''cells in the heart's outer layer can migrate deeper into a failing organ to carry out essential repairs. The migration of progenitor cells is controlled by a protein called thymosin beta 4, already known to help reduce muscle cell ...

The Chemical & Engineering News notes another group working on enhanced healing via nanofibers: researchers ''combined neural stem cells [with] carbon nanofibers and injected the cocktail into damaged regions of the brains of rats that had suffered a simulated stroke. After a few weeks, [nanofibers] with stem cells promoted the growth of new ...

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 ...
