Summary
Cellular magnetic resonance imaging (CMRI) tracks cell migration using contrast agents. Preclinical evaluation is crucial for translating CMRI cell tracking from research to clinical applications.
Area of Science:
- Biomedical Imaging
- Cellular Biology
Background:
- Cellular magnetic resonance imaging (CMRI) enables tracking of cell migration in vivo.
- This technique holds promise for cellular therapies and drug development.
Purpose of the Study:
- To review the principles and applications of CMRI for cell tracking.
- To highlight the necessity of preclinical evaluation for clinical translation.
Main Methods:
- Ex vivo labeling of nonphagocytic cells using superparamagnetic iron oxide nanoparticles or paramagnetic contrast agents (gadolinium, manganese).
- Detection of labeled cells using CMRI after implantation or injection.
Main Results:
- CMRI allows for detection of single cells or clusters within tissues.
- Successful cell tracking has been demonstrated in experimental settings.
Conclusions:
- Preclinical assessment is essential for CMRI clinical translation.
- Demonstrating lack of toxicity, scalability, and in vivo detectability is required.
