Comparison of iron oxide labeling properties of hematopoietic progenitor cells from umbilical cord blood and from peripheral blood for subsequent in vivo tracking in a xenotransplant mouse model XXX1

Hematopoietic progenitor cells from umbilical cord blood can be labeled by simple incubation with an Food and Drug Administration-approved magnetic resonance contrast agent with sufficient efficiency to provide an in vivo cell tracking at 1.5 T. Progenitor cells from peripheral blood need to be labeled with adjunctive transfection techniques to be depicted in vivo at 1.5 T.
