To aid the recovery, clinicians inject patients with proteins called growth factors. The treatment is costly, requiring large amounts of expensive growth factors. The growth factors also disperse, creating unwanted bone formation in the area around the injury.\u003C\/p\u003E\u003Cp\u003EA new technology under development at the Georgia Institute of Technology could one day provide more efficient delivery of the bone regenerating growth factors with greater accuracy and at a lower cost.\u003C\/p\u003E\u003Cp\u003EIn a recent study, researchers bound the most clinically-used growth factor with microparticles of the drug heparin at concentrations up to 1,000-fold higher than previously reported. The growth factor, called bone morphogenetic protein-2 (BMP-2), also remained bioactive after long periods of time spent bound to the microparticles.\u003C\/p\u003E\u003Cp\u003E\u201cThe net result is more efficient and spatially controlled delivery of this very potent and very valuable protein,\u201d said \u003Ca href=\u0022http:\/\/www.me.gatech.edu\/faculty\/mcdevitt\u0022 target=\u0022_blank\u0022\u003ETodd McDevitt\u003C\/a\u003E, a professor in the Wallace H.
