Objective: To investigate the feasibility of using decalcified bone matrix loaded with mesenchymal stem cells (MSCs) derived from adult human bone marrow as scaffolds for bone tissue engineering.
Methods: Allogenic decalcified bone matrix was prepared. MSCs were isolated from adult human bone marrow with monocyte-separating medium and then cultured in basic medium of mesenchymal stem cells (MSC). The third generation of the cultured cells were identified by FITC-antiCD105, seeded onto allogenic decalcified bone matrix followed by observation under scanning electron microscope and invert microscope a week later.
Results: Rapid proliferation of both primary and subcultured MSCs was observed, and CD105-positive cells reached 64.1% among the third generation of the cells. MSCs also grew well and proliferated rapidly after being cultured with decalcified bone matrix.
Conclusion: Naive MSCs are ideal seeding cells for bone tissue engineering, and the allogenic decalcified bone matrix loaded with MSCs may be used as a good scaffold.
