Scientists have developed a new biomaterial that helps bones heal faster by enhancing adults’ stem cell regenerative ability.
The study, led by researchers from RCSI University of Medicine and Health Sciences and CHI at Temple Street, is published in the current edition of Biomaterials, the highest ranked journal in the field of biomaterials science.
The researchers had previously discovered a molecule called JNK3, which is a key driver of children’s stem cells being more sensitive to their environment and regenerating better than adults’. This explains, at least partially, why children’s bones are able to heal more quickly. Building on this knowledge, they created a biomaterial that mimics the structure of bone tissue and incorporates nanoparticles that activate JNK3.
