Stem cell transplantation has emerged as a promising treatment strategy for stroke. The development of effective ways to
monitor transplanted stem cells is essential to understand how stem cell transplantation enhances stroke recovery and ultimately will be
an indispensable tool for advancing stem cell therapy to the clinic. In this review, we describe existing methods of tracking transplanted
stem cells in vivo, including optical imaging, magnetic resonance imaging (MRI), and positron emission tomography (PET), with emphasis
on the benefits and drawbacks of each imaging approach. Key considerations such as the potential impact of each tracking system on
stem cell function, as well as its relative applicability to humans are discussed. Finally, we describe multi-modal imaging strategies as a
more comprehensive method to track transplanted stem cells in the stroke-injured brain.
