Effect of lactoferrin-impregnated porous poly(lactide-co-glycolide) (PLGA) microspheres on osteogenic differentiation of rabbit adipose-derived stem cells (rADSCs)

- Porous microspheres were successfully modified using heparin-dopamine and lactoferrin.
- Lactoferrin impregnated on Hep-PMSs has sustained release profiles for 28 days.
- Lactoferrin impregnated on Hep-PMSs showed induced osteogenic differentiation.
