Table 1 Comparison of detection techniques

From: Multimodal in vivoimaging reveals limited allograft survival, intrapulmonary cell trapping and minimal evidence for ischemia-directed BMSC homing

  Bioluminescence imaging Confocal endomicroscopy
Strength Non-invasive High spatial resolution
  Low background signals Single cell imaging
  Highly specific for Luciferase activity Cell morphology studies
Weakness Low spatial resolution Invasive procedure
  Low cell numbers not detectable Requires direct probe contact
  Limited tissue penetration Autofluorescence reduces specificity
  Superior specificity Superior spatial resolution
