| Research Abstract |
The uptake of D-glucosamine hydrochloride into cultured osteoblasts was directly observed using D-glucosamine-conjugated carboxylated quantum dots for efficient labeling of cells. Quantum dots attached at cell surface and were transported into cytoplasm at approximately 3 hours of culture. Furthermore, although the intranuclear distribution was not confirmed, the decrease of quantum dots was recognized in cytoplasm at approximately 7 days of culture.
