Ceramic particles promote bone repair

A new study shows how particles of the ceramic have the ability to stimulate promising bone regrowth by attracting stem cells and natural growth factors that encourage tissue growth to promote healing and integration of the grafted tissue.

‘The rate of bone repair we see with these materials rivals that of traditional grafts using a patient’s own bone,’ said Prof Joost de Bruijn from the School of Engineering and Materials Science at Queen Mary, University of London. ‘And what sets it apart from other synthetic graft substitutes is its ability to attract stem cells and the body’s natural growth factors, which coincide to form new, strong, natural bone around an artificial graft.’

The researchers tested natural bone grafts against ceramic particles with varied structural and chemical properties. They are reported to have found that microporous ceramic particles composed of calcium phosphate, the primary component of bone ash, induced stem cells to develop into bone cells in the lab and stimulated bone growth in live tissue in mice, dogs and sheep.
