BCL6 confers a growth advantage to primary human B cells. (A) Two independent batches of primary human tonsillar B cells were infected with retroviral vectors expressing either GFP (●) or BCL6 and GFP (○). The percentage of GFP-positive cells was followed over time in culture. (B) Western blot analysis of BCL6, cyclin D1, and control CDK4 expression in primary human B cells in culture and BCL6-infected derivatives.
