Visualization of gene expression of TFs using Amazonia “B cell to PC Atlas.” The gene expression of the 54 613 Affymetrix probe sets in MBCs, D4 actBCs, D7 PBs, D10 PCs, and BMPCs can be visualized using the Amazonia web site (http://amazonia.transcriptome.eu/). The known interactions of these TFs are displayed in panel A. Data are the expression of genes coding for TFs controlling B-cell and PC fate (B). *The mean expression is different from that in D0 MBCs. **The mean expression is different from that in D4 actBCs. ***The mean expression is different from that in D7 PBs. #The mean expression is different between D10 PCs and BMPCs.
