“Finally, we demonstrated that daidzein stimulated Col I, Runx2, and ALP expression, while these effects were significantly blocked by the BMP signaling inhibitor noggin.”
“Here, we … that daidzein stimulated cell proliferation and differentiation of osteoblasts, demonstrated … upregulation of XTT activity, enhancement of alkaline phosphatase ( ALP ) activity, and upregulation of osteoblast-specific marker genes, including Runt-related transcription factor 2 (Runx2) and Smad1, as well as up-regulation of Runx2 and Smad1 protein expression.”
