Absolute numbers of PC (CD138+B220lo) after ABT-737 treatment of lethally irradiated mice reconstituted with Bcma−/− BM, performed as in Figure 4. Data represent one experiment and six animals per group. **P⩽0.01 (Statistical significance was calculated between the groups using a Mann–Whitney test)
