The aim of this research work was to investigate in vitro effect of the carbonate apatite/poly(ε- caprolactone) (CO3Ap/PCL) on α-tricalcium phosphate (α-TCP) foam. α-TCP was produced by sintering CaCO3 and CaHPO4•2H2O at 1500°C for 5 h. It was then coated with CO3Ap/PCL (wt/wt=1/3) to improve both mechanical and biological properties. The initial cell attachment and proliferation of the bone marrow cells were carried out on the α-TCP and CO3Ap/PCL-coated α- TCP foams. The cell proliferation was calculated by AlamarBlue assay. The cells were able to migrate and proliferate well on both α-TCP and CO3Ap/PCL-coated α-TCP foams indicating an excellent biocompatibility. The incorporation of CO3Ap on the coating layer improved cellular attachment and accelerated proliferation. Thus, CO3Ap/PCL-coated α-TCP foam might be a promising candidate as implant material.
