Biomaterial Keeps Bone-Healing Protein in Place

Biomaterial Keeps Bone-Healing Protein in Place
Wrapping a bone-healing biomaterial in alginate and herapin offers an effective form of treatment with fewer side effects.

The bone-forming protein called bone morphogenetic protein (BMP) is known to stimulate bone growth, but also triggers unwanted growth in the surrounding tissue. To help keep the protein more contained, researchers from the University of Oregon wrapped the BMP in a biomaterial made up of an alginate gel and the anticoagulant herapin. This material can be injected into the injury site, where it holds the healing BMP in place and reduces the risks of unwanted growth.
