The images of MSCs and the IronQ-labeled MSCs from an inverted phase-contrast microscope and 3.0 T MRI. A Identification results of MSCs by flow cytometry. B MSCs at passages 3–6 grew in a cluster shape. Scale bar = 100 μm. C, D The images of MSCs incubated without (B) and with (C) IronQ for 24 h were checked by Prussian blue staining. Scale bar = 100 μm. E MTT assay of IronQ for MSCs. F T1W images of mice brains in the coronal plane, axial plane, and sagittal plane of the sham operation, model, and MSCs + IronQ groups. Arrow indicated a hemorrhage (dark) area and IronQ-labeled MSCs (a white spot) in the hemorrhage (dark) area of the ipsilateral striatum in the brain tissue of ICH mice. Scale bar = 1 cm
