A) MEMRI Signal in Infarct Zone. Note the discrete regions of increased signal intensity on MEMRI imaging (top panels, white arrows on consecutive shot-axis images) within areas of infarction, as denoted by corresponding DEMRI panels below. B) Immunohistochemistry for human Nuclear Antigen (hNA) taken from the infarct zone of a hAMSC-treated heart. Bright green cells represent positive-staining hAMSCs that are abundant within the infarct zone 17 days after transplantation, representing a potential source for increased MEMRI signal in this region.
