چکیده انگلیسی
Chitosan (CS) was used to modify the surface of apatite-wollastonite bioactive glass ceramic (AW GC) scaffold to prepare AW/CS composite scaffold. The in vitro bioactivity of the AW/CS composite scaffold was investigated by simulated body fluid (SBF) soaking experiment. Cell growth on the surface of the material was evaluated by co-culturing osteogenic marrow stromal cells (MSCs) of rabbits with the scaffold. The results showed that the compressive strength of AW GC scaffold was improved dramatically after being modified by CS, whereas the mineralization rate was delayed. MSCs can attach well on the surface of the composite scaffold.
