Figure 2

Fluorescent images and signal-to-background ratio of quantum dot (QD)800 tagged C4-2B cells at (A) subcutaneous or (B) intratibial sites to establish minimal number of cells that could be detected by fluorescent imaging. (C) One million QD800-tagged C4-2B cells injected at different sites show effects of tissue depth on fluorescent signal. F, femur; T, tibia; S, subcutis. C4-2B cells previously tagged with QD800 inoculated subcutaneously or intraosseously. Data collected from 3 mice for each group with specific cell number of cancer cells.
