[The study of cell biocompatibility of new pattern biphasic calcium phosphate nanocomposite in vitro].

Objective: To study the cell biocompatibility of porous biphasic calcium phosphate nanocomposite in vitro.

Methods: Bone marrow mesenchymal cell (BMSCs) obtained from SD rat bone marrow were in vitro induced and proliferated. Afler their osteoblast phenotypes were verified, BMSCs were seeded onto prepared porous biphasic calcium phosphate nanocomposite (Experiment group) and common porous hydroxyapatite (Control group).
