Osteogain® loaded onto an absorbable collagen sponge

Osteogain® loaded onto an absorbable collagen sponge induces attachment and osteoblast differentiation of ST2 cells in vitro. Miron et al. RESULTS: ACS efficiently loaded nearly 100% of the amelogenin proteins found in Osteogain® which were gradually released up to a 10-day period. Osteogain® also significantly induced a 1.5-fold increase in...
