Figure 8. Effect of soluble factor from HA powder and Ti powder on the proliferation of MC3T3-E1 cells. (A) SEM image of HA powder and Ti powder. (B) The cells were seeded on the HA plate (left panels) and fibronectin-coated culture plate (right panels). The proliferation of MC3T3-E1 cells was evaluated by WST-1 assay. *p<0.05 vs. the corresponding control group.
