The Effect of Stromal-Derived Factor 1α on Osteoinduction Properties of Porous β-Tricalcium Phosphate Bioceramics

Figure 2

Electron microscopic view of the surface of the porous TCP bioceramics: (a) without pretreatment, the surface is smooth and not suitable for loading drugs; (b) after pretreatment, the surface becomes rough and can do well in drug loading; (c) TCP loaded with SDF-1α and Ca-P deposition.
