Cell therapy is a proven and efficient method for treating multiple diseases. For both basic research and clinical practice, the development of noninvasive in vivo imaging methods is essential for monitoring the trafficking or homing of transplanted cells. One attractive approach for the effective imaging of transplanted cells is the efficient labeling of cells with a contrast agent. In this study, we developed a novel contrast agent of magnetic resonance imaging (MRI), TMADM-02. TMADM-02 was efficiently transduced into cells without toxicity. However, the aggregation of TMADM-02 was observed because of its low stability in culture medium. Therefore, TMADM-02 may have led to a false-positive test result. In future studies, we should verify not only the efficiency of labeling cells but also the stability of the contrast agent of MRI for clinical applications.

More about this publication?
  • Cell Transplantation publishes original, peer-reviewed research and review articles on the subject of cell transplantation and its application to human diseases. To ensure high-quality contributions from all areas of transplantation, separate section editors and editorial boards have been established. Articles deal with a wide range of topics including physiological, medical, preclinical, tissue engineering, and device-oriented aspects of transplantation of nervous system, endocrine, growth factor-secreting, bone marrow, epithelial, endothelial, and genetically engineered cells, among others. Basic clinical studies and immunological research papers are also featured. To provide complete coverage of this revolutionary field, Cell Transplantation will report on relevant technological advances, and ethical and regulatory considerations of cell transplants. Cell Transplantation is now an Open Access journal starting with volume 18 in 2009, and therefore there will be an inexpensive publication charge, which is dependent on the number of pages, in addition to the charge for color figures. This will allow work to be disseminated to a wider audience and also entitle the corresponding author to a free PDF, as well as prepublication of an unedited version of the manuscript.
