SPIO-labeled human neural precursor stem cells can be tracked in longitudinal MR studies. Mice were stereotactically implanted in R hemisphere with 2.5 × 103 viable Endorem-labeled cells and in the contralateral hemisphere (L) with the same number of cells labeled with Endorem plus PLL. One day after implantation, cells were detectable at the injection sites as hypointense spots in T2 images. The MR signal remained stable up to the latest time point (28 days) analyzed.
