Stem cell tracking system promises more targeted regenerative therapies

Stem cells hold enormous potential for repairing or regenerating damaged tissue. But delivery of these cells to their target location remains a major obstacle. Now, researchers at the Stanford University School of Medicine in California have developed a novel nanoparticle-based system that allows stem cells to be tracked in real time in a living mouse for up to a year after injection. This work, if replicated in humans, could finally allow scientists to verify if these cells are going where they’re intended.
