Figure 3From: Optimized labeling of bone marrow mesenchymal cells with superparamagnetic iron oxide nanoparticles and in vivo visualization by magnetic resonance imagingEvaluation of MSC viability after exposure to FeProt complexes. (A-C) Viability was measured by live/dead assays in live MSCs incubated with FeProt complexes for 4 or 24 hrs. No change in MSCs viability was observed at different time points (A) MSCs exposed to FeProt complexes for 4 or 24 hrs. (B-C) Viability of MSCs cultured for up 7 days after initial exposure to FeProt complexes for 4 hrs. (B) 3 days after initial incubation. (C) 7 days after initial incubation. (N = 9, for each group). Error bars represent SEM.Back to article page
