Bioprinting bone with genes for growth factors improves bone repair

In a method that helps promoting regeneration and healing in skulls of animals, such as rats, scientists at Penn State, with support from a U.S. National Science Foundation grant, are "bioprinting bone with encoding genes that enhance healing and regeneration. The researchers successfully used the technique on rat skulls and published the results in Biomaterials."

"The team combined a platelet-derived growth factor and a protein that improves regeneration via bioprinting and used a controlled co-delivery release. The encoding genes the team developed were printed to rat skulls during surgery and resulted in more bone creation and coverage. " reports the National Science Foundation website.
