Detection of intravenously infused HUCBC ex vivo. High resolution imaging with isotopic 50µm voxel resolution on 14.1T magnet. Agarose phantoms without (A) and with Feridex labeled (B) cells. Rectangle ROIs placed on phantoms are shown with high magnification. Note punctate hypo-intensities in panel B, indicating labeled cells. Perfusion fixed brain of E32 kit infused with media (C) or Feridex labeled cells (D). Arrows point to choroid plexus on C and D. Scale bar 1 mm. E .PCR for human DNA showing most of cortex and thalamus samples having some small amounts of human DNA.
