In vivo homing of BCR/ABL-expressing cells. Single-cell suspensions were prepared from bone marrow (BMC) and spleen (SPL) of mice 24 (▪) and 48 (▨) hours after injection with [3H]-uridine–labeled 32Dcl3 clones (A) or retrovirus-infected BMC (B) and deposited onto glass microfiber filters. Cell-associated radioactivity was determined as described in the Materials and Methods. Results are expressed as the percentage of injected radioactivity (mean ± SD from 3 mice in each group).
