3- Natural killer (NK) cells

B lymphocyte development

stem cell

Pro B cells

CD19,CD10, µ heavy chain rearrangement

Pre B cells

Pre antigen receptor expression

 immature B cells

IgM BCR expression,independent of antigen and their encounter with it ,receptor editing,cell death,functional unresponsiveness

Mature B cells
