Noni leaf extract increased the activity of alkaline phosphatase (ALP) and expression of osteoblast differentiation markers. The extract also increased matrix mineralization of hPDL cells. These results suggest that noni leaf may enhance osteogenic differentiation. (original abstract available at https://www.ncbi.nlm.nih.gov/pubmed/28981378).
