Dataset: Generation of hematopoietic progenitor cell lines with myeloid and lymphoid potential using a conditional form of Hoxb8

Investigation of immune cell differentiation and function is limited by shortcomings of suitable and scalable experimental systems. Although forced expression of certain Hox genes allows immortalization of hematopoietic progenitor cells, their differentiation potential is limited to select myeloid lineages. Here we show that an estrogen-regulated form of Hoxb8 that is retrovirally delivered into bone marrow cells can be used along with FLT3 ligand to conditionally immortalize early hematopoietic progenitor cells (Hoxb8-FL). Hoxb8-FL cells have lost self-renewal capacity and the ability to adopt megakaryocyte/ erythroid lineage fates, but sustain myeloid and lymphoid differentiation potential. Hoxb8-FL cells differentiate in vitro and in vivo into different myeloid and lymphoid cell types, including macrophages, granulocytes, dendritic cells and B- and T-lymphocytes, which are phenotypically and functionally indistinguishable from their primary counterparts. Given the simplicity to generate Hoxb8-FL cells and their unlimited proliferative capacity, this system provides unique opportunities to investigate cell differentiation and immune cell functions.
