3. This new hydrogel can regrow bone in skulls
Illinois researchers were able to regrow bone and repair a hole in a mouse’s skull, thanks to a hydrogel.
The Northwestern University and University of Chicago-based researchers were able to regenerate skull bone and supporting blood vessels a lot faster than previous bone regrowth methods.
Researchers engineered harvested mouse skull cells to create a BMP9 protein that promotes bone growth. Then they delivered the protein to the area using a hydrogel. The hydrogel formed a temporary scaffold while the engineered skull cells regrew.
