In many ways, our bodies have a tremendous capability to heal themselves, but occasionally they do need help. Of course the catch with giving our bodies help is making sure it does not fail or ultimately hurt the body. Researchers at Rice University have recently developed a hydrogel that solves the problem of others, when it comes to guiding our bodies to repair damage to bones. One of the ways a doctor can help our bodies heal is to provide a scaffold for our cells to grow on.
