Ms) for an extra two d to achieve cell differentiation. Where indicated, cells were treated with 30 M of Erk1/2 inhibitor (FR180204; EMD Chemicals), five M PI3K inhibitor (Ly294002; EMD Chemicals), DMSO (Sigma), or 20 g/mL of LPS (Sigma; L3755) during culture with BAFF. Retroviral transduction of immature B cells was performed as previously described (19). Generation of “Retrogenic” Bone Marrow Chimeras. Transduction of bone marrow cells from donor 33Igi,H-2d and B1/33Igi,H-2d mice was performed with two cycles of spin infection as previously described (19). Recipient CB17,H-2b mice had been lethally irradiated as previously described (19) and received a total of 2 105 donor cells in PBS CDK16 Molecular Weight through tail vein injection. Mice had been analyzed three or five wk later. Quantitative Real-Time RT-PCR. Transduced and nontransduced B cells from in vitro bone marrow cultures (day 2 after BAFF addition) and from retrogenic bone marrow chimeras (week three soon after reconstitution) have been isolated utilizing Synergy (iCyt) or Mo-FLO XDP (Beckman Coulter) cell sorters.
