Through the ordered and sequential activation of a series of transcription factors the cell first becomes committed to the lymphoid lineage and then gives rise to B and T cells. About 75 of all lymphoid leukemias and 90 of all lymphomas are of B cell origin. A cell becomes committed to B cell development when it begins to rearrange its immunoglobulin genes. The sequence of cellular changes including changes in cell-surface phenotype that characterizes normal
