Immobilization of bone morphogenetic protein‐2 on a nanofibrous chitosan membrane for enhanced guided bone regeneration
Abstract
BMP‐2 (bone morphogenetic protein‐2) has been used in promoting bone formation and, in combination with various delivery carriers, in bone regeneration or bone tissue‐engineering practice. In the present study, BMP‐2 was immobilized directly on a GBR (guided bone‐regenerative) membrane surface made of chitosan nanofibres, providing a bioactive surface that can enhance bone‐regeneration capacity. The BMP‐2‐conjugated membrane surface retained bioactivity for up to 4 weeks of incubation, as well as holding over 50% of the initial BMP‐2 attached. The BMP‐2‐conjugated surface increased osteoblastic cell attachment in accordance with the amount of BMP‐2 conjugated. In addition, the BMP‐2‐conjugated chitosan membrane significantly promoted cell proliferation, alkaline phosphatase activity, as well as calcium deposition when compared with BMP‐2‐adsorbed membrane, indicating a stable localization of BMP‐2 at the surface of the chitosan membrane. Taking these findings together, the conjugation of BMP‐2 on a chitosan nanofibrous membrane would seen to be applicable for inducing significant and localized bone formation in future GBR procedures.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
