Bone Scaffold From Bacteria

An interesting article surfaced in the Daily Beacon on the use of bacteria to build scaffold material for transplant and bone regeneration. "Hutchens's idea for using bacterial cellulose to replicate bone began four years ago ... These bacteria are like spiders that swim around and weave this pure cellulose into a mesh ... We just lift off that layer, clean it, and then we are ready to use it. It is similar to tissue ... Comparing her synthetic calcium-phosphate material to actual bone, Hutchens found that the nanostructure was very similar. ... Whether this bioengineered bone will grow in the body is unknown, but that is the UTK student's next research step. Hutchens is preparing the paperwork required to conduct a biological study where she will implant her bone-like gel into an animal model. That test will determine whether the bone gel can attract developing bone cells, or osteoblasts, to an injured area and elicit bone regeneration." Past studies show that the right sort of scaffold material makes all the difference in enhancing regeneration in the body.
