| Research Abstract |
Induced pluripotent stem cells (iPSCs) Labeling by 64-Cu positron emitting isotopes is a technical success with using PTSM material as a binding material. And positron emission tomography (PET) images which indicate iPSC distributions were acquired successfully. Two administration pathways were used ; 1) intravenous injection via tail vein, 2) left ventricle injection directly. There was significant difference between each distribution. Only lung distribution was seen by intravenous injection. On the other hand, the distributions to brain, kidneys, and transplanted tumors were described. Since half-life for 64-Cu is 13 hours, PET images could be acquired at 24 hours after labeled cells injection. Comparison with images for 18F-FDG labeled iPSCs, 64-Cu labeled image has less signal-to-noise ratio than that of 18F-FDG within 6 hour after positron-labeled cells administration.
