The first lymphoid restricted progeny of HSCs are lymphoid-primed multipotent progenitors (LMPPs), which have little erythro-myeloid potential but retain lymphoid and granulocyte/macrophage differentiation capacity. Despite recent advances in the identification of LMPPs the transcription factors essential for their generation remain to be identified. Here we demonstrate that the E2A transcription factors are required for proper development of LMPPs. Within HSCs and LMPPs, E2A proteins prime expression of a subset of lymphoid-associated genes and prevent expression of genes that are not normally prevalent in these cells, including HSC-associated and non-lymphoid genes. E2A proteins also restrict proliferation of HSCs, MPPs, and LMPPs and antagonize differentiation of LMPPs toward the myeloid fate. Our results reveal that E2A proteins play a critical role in supporting lymphoid specification from HSCs and that the reduced generation of LMPPs underlies the severe lymphocyte deficiencies observed in E2A-deficient mice.
