In vivo analysis of the survival of SPIO-labeled hiPS-CMs after transplantation. (a) Serial CMRs were examined at 1 week (baseline), 1 month, 2 months, and 3 months after SPIO-labeled hiPS-CM cell-sheet transplantation, with or without the omentum. (b) Cell survival proportion was estimated by the SPIO-labeled area at 1 month, 2 months and 3 months, corrected by cell survival at 1 week. (c,d) Cells containing iron, indicative of SPIO-labeled hiPS-CMs, were detected by Prussian Blue staining of sections of the S group (c) or the SO group (d) at the transplanted area; bar = 50 μm in (c,d).
