Stem Cell Tracking Technologies for Neurological Regenerative Medicine Purposes

الملخص EN

The growing field of stem cell therapy is moving toward clinical trials in a variety of applications, particularly for neurological diseases.

However, this translation of cell therapies into humans has prompted a need to create innovative and breakthrough methods for stem cell tracing, to explore the migration routes and its reciprocity with microenvironment targets in the body, to monitor and track the outcome after stem cell transplantation therapy, and to track the distribution and cell viability of transplanted cells noninvasively and longitudinally.

Recently, a larger number of cell tracking methods in vivo were developed and applied in animals and humans, including magnetic resonance imaging, nuclear medicine imaging, and optical imaging.

This review has been intended to summarize the current use of those imaging tools in tracking stem cells, detailing their main features and drawbacks, including image resolution, tissue penetrating depth, and biosafety aspects.

Finally, we address that multimodality imaging method will be a more potential tracking tool in the future clinical application.
