PCR analysis of DJ_H and VDJ_H gene rearrangements on DNA from differentiated CD19⁺, CD56⁺, and CD14⁺ cells generated by CD79a⁺-enriched CDw127⁺CD11b^–CD36^–CD19^– cells. (A) BLIN1 and CD34^–CD19⁺ were used as controls as described in the legend of Figure 4. CD19⁺ B cells, CD56⁺ NK cells, and CD14⁺ macrophages were obtained from cultured CD79a⁺-enriched CDw127⁺CD11b^–CD36^–CD19^– cells and sorted twice at day 28 (> 98% purity). DNA was extracted from 20 000 cells, and PCR was performed as described in “Materials and methods.” (B) Results of PCR performed on serial dilutions of DNA extracted from CD19⁺ cells purified at day 28 as described in panel A.
