FIG. 2.

The bioluminescent signal at selected time points from a representative experimental animal with particle infusion in the left femur. By day 4, the signal begins to localize at the left femur. The intensity of the signal in the left femur compared to the intensity of the signal elsewhere increases throughout the experiment. White arrows denote a signal in the left femur. The MAX values listed indicate the maximum luminescence value in the image (the value corresponding to the red regions). Color images available online at www.liebertpub.com/tea
