Ex vivo biodistribution analysis of BM-DC homing. (A) Relative biodistribution (relative light units normalized per milligram of tissue) of Luc⁺ DCs in NOD and FVB mice on day 3 and day 5 after intravenous or intraperitoneal injection. (B) Relative biodistribution of Luc⁺ DCs in FVB mice on days 1, 3, 6, and 12 after intravenous or intraperitoneal injection. See Table 1 for tissue legend (left lobe of the liver was used). All data show the mean from 3 mice ± SE.
