title: Seeding osteoblastic cells into a macroporous biodegradable CaP/PLGA scaffold by a centrifugal force.
abstract: This study aims to construct a hybrid biomaterial by seeding osteoblastic cells into a CaP/PLGA scaffold by a centrifugal force. Constructs are evaluated with respect to potential application in bone tissue engineering. Cells adher, spread, and form a layer of tissue lining the scaffold and are capable of migrating, proliferating, and producing mineralized matrix. We have demonstrated that the centrifugal force is highly efficient for constructing a hybrid biomaterial, which acts similarly to bone explants in a cell culture environment. In this way, these constructs could mimic an autogenous bone graft in clinical circumstances. Such a strategy may be useful for bone tissue engineering.
