Objective: To investigate the release of bone morphogenetic protein-2 (BMP-2) and collagen type I proteins (COL1) from different sources ofdemineralized dentine matrix (DDM) and their chemotaxis to mouse osteoprogenitor cells.Methods: The release kinetic of BMP-2 and COL1 was measured from custom-made DDM (CMDDM) and commercially available DDM (CADDM).Using Urist physicochemical method, CMDDM was collected from the extracted teeth in a certified dental clinic. Levels of BMP-2 and COL1 releasedwere measured at days 1, 2, 3, 5, 7, 9, 11, and 13. Next, mouse osteoprogenitor cells, MC3T3-E1, were cultured with a variety of materials as follows:CMDDM, CADDM, Bio-Oss®, and blank control in transwell system. The number of cell migration was determined by crystal violet staining to explorechemotaxis of different DDMs to mouse osteoprogenitor cells.Results: BMP-2 was detected at 588.32 ± 14.53 pg/ml from 5 g of CMDDM. In the release kinetic assay, the concentration of BMP-2 in the CMDDMgroup increased rapidly and peaked at 113.9 pg/ml on day 5, almost four times higher than that of CADDM. The release of COL1 showed similarpattern in both CMDDM and CADDM; however, the amount was significantly higher in the CMDDM group. In cell culture experiment, the number ofmigrated MC3T3-E1 was ranked as the highest in CMDDM, followed by CADDM and Bio-Oss® (p<0.05).Conclusion: CMDDM released BMP-2 and COL1 greater than CADDM, which can induce more osteoblast-like cell migration. These results demonstrateda release kinetic of proteins and osteoinductivity of CMDDM, which supports a benefit of using autogenous bone graft.
