Popis: Abstract Following infection or vaccination, early-minted antibody secreting cells (ASC) or plasmablasts appear in circulation transiently, and a small fraction migrates to the spleen or bone marrow (BM) to mature into long-lived plasma cells (LLPC). While LLPC, by definition, are quiescent or non-dividing, the majority of blood ASC are thought to be “blasting” or proliferative. In this study, we find > 95% nascent blood ASC in culture express Ki-67 but only 6–12% incorporate BrdU after 4 h or 24 h labeling. In contrast,
