In vivo QD fluorescence—live versus devitalized hMSCs study. Femoral bone defects were treated by delivery of scaffolds containing either 3E6 or 6E6 QD-loaded live hMSCs, 3E6 or 6E6 QD-loaded devitalized hMSCs, or 6E6 QD-loaded HEK cells, with contralateral defects receiving acellular scaffolds only. Ten days later, all defects displayed a clear fluorescent signal.
