Figure 2. Physicochemical properties of CAH/B2 scaffolds.

Figure 2

A. SEM view of CAH/B2 scaffold at a magnification of 100×, B. SEM view of CAH/B2 scaffold at a magnification of 200×. SEM analysis showed that micro-pores were generated in the CAH scaffold, the average pore diameter in the scaffold being 100–110 µm. C. In vitro release behavior of BMP-2 from the CAH scaffold. Col/B2 served as a control. The release velocity of BMP-2 was delayed in the CAH/B2 group compared with release from Col/B2. The cumulative BMP-2 released from the CAH/B2 and the Col/B2 groups almost reached a plateau at 21 and 14 days, respectively. D. SEM view of MSCs cultured on a CAH/B2 scaffold at a magnification of 100×.
