MSC-patch engraftment and SPECT exams. A: example of ventricular surgical engraftment of MSC-patch. B: representative serial images provided by Sestamibi pinhole-SPECT in a treated rat; (a) pre-therapeutic perfusion SPECT assessment of chronic MI (MI segments with defect of perfusion, white arrow), (b) early post-operative MSC-patch tracking (labelled ¹¹¹In-MSC-patch detected 48-hours after patch engraftment) and (c) one month post-operative perfusion SPECT assessment after MSC-patch treatment (MI segments with enhanced perfusion, white arrow).
