Abstract:

BACKGROUND: Stem cell therapy research has been able to continue to observe the different types of stem cells, but there is still no single imaging mode for a comprehensive evaluation of the effect of stem cell therapy.
OBJECTIVE: To review the tracing of cell markers and imaging technology in stem cell therapy and to prospect the clinical application of molecular imaging in stem cell therapy.
METHODS: The first author retrieved the PubMed for articles (January 2005 to December 2012) regarding application of molecular imaging in stem cell therapy, cell marking methods and imaging technology, ideal imaging mode for stem cell therapy, and tracing of different stem cells using molecular imaging method. The key words were “molecular imaging, stem cell therapy, cell transplantation, regenerative medicine” in English. Twenty of 269 papers were included in result analysis.
RESULTS AND CONCLUSION: At present, the ability to continuously monitor the biological processes of the transplanted stem cells relies on the histological analysis at different times. However, molecular imaging can observe in vivo complex system functions at the molecular, cellular, organ, and whole body level. As the technology improves, the change in the molecular level can be assessed in the context of the living organism. At the same time, a number of methods are available and meeting the demands to track stem cells by molecular imaging. Imaging technology increases the feasibility of stem cell therapy, and contributes to clarify the new biological mechanism during the stem cell therapy.

Key words: stem cells, cell transplantation, regenerative medicine
