In this experiment, it was shown that cultured PDLSCs proliferate in higher rate on the rough surface especially at the 75 μm Al(2) O(3) particle treated surface than other surfaces. Also, osteocalcin was highly expressed on the rough surfaces treated with 75 μm and 125 μm Al(2) O(3) particles.
In patients with FD, stem cells in affected bone are influenced by the mutation, resulting in weak bone formation with the proliferation of immature osteogenic cells. Current treatment of FD involves surgical removal of excess bulk lesions, which can cause facial disfigurement. Our results suggest that BMP-2 application is a good adjunctive modality to the surgical treatment of patients with FD.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
