- Abstract
- The aim of this study is to fabricate lactoferrin (LF)-carrying hydroxyapatite nanoparticles (HAp NPs) to enhance osteogenic differentiation of rabbit adipose-derived stem cells (rADSCs). HAp NPs were modified with heparin-dopamine (Hep-DOPA) (Hep-HAp) and further immobilized with LF (LF/Hep-HAp). Heparin immobilization on HAp NPs prevented aggregation of HAp NPs in aqueous solution and prolonged the release of LF from LF/Hep-HAp NPs. In vitro studies of rADSCs have demonstrated that LF-Hep/HAp NPs significantly increase alkaline phosphatase (ALP) activity, calcium deposition, and both mRNA expression of osteocalcin (OCN) and osteopontin (OPN) in comparison with HAp and Hep-HAp NPs. These results suggest that LF/Hep-HAp NPs can effectively induce osteogenic differentiation of rADSCs.
