Effect of BMP-2 Delivery Mode on Osteogenic Differentiation of Stem Cells
Figure 2
Schematic representation of culture system on alginate hydrogel disc used to assess the effect of BMP-2 delivery mode on osteogenic differentiation of human BM-MSCs and photographs of ALP stained human BM-MSCs. (a) Top-down release system, (b) bottom-up release system, and (c) quantification of ALP activity for BM-MSCs cultured under each mode of delivery. The values represent the mean ± standard deviation (). compared with top-down release system at 7 days.
