Dentonin (AC-100) is a synthetic fragment derived from MEPE. Dentonin enhances osteogenesis by promoting osteoprogenitor adhesion and facilitates immature adherent cells survival. Dentonin has no significant effect to mature osteoblasts. Dentonin can be used for the research of phosphate homeostasis and bone metabolism[1].
MEPE is a a member of the SIBLING (Small Integrin-Binding Ligand, N-linked Glycoprotein) family of secreted glycophosphoproteins. MEPE regulates bone mass and influence osteoblast activity.[1].
Dentonin (3-30 μg/ml; 2-24 hours) significantly increases the numbers of cell and shows enhanced promotion of cell adhesion. However, it has no significant differences in terms of numbers of cells adhered[2].
Dentonin (3-30 μg/ml; 2-24 hours) enhances osteoblast spreading, it exhibits significantly increased cell areas compared to all other treatment[2].
