Abstract Background Human embryonic stem hES cells hold considerable promise for cell replacement and gene therapies. Their remarkable properties of pluripotency self-renewal and tractability for genetic modification potentially allows for the production of sizeable quantities of therapeutic cells of the hematopoietic lineage. Dendritic cells DC arise from CD34 hematopoietic progenitor cells HPCs and are important in many innate and adaptive immune functions. With respect to HIV-1 infection DCs play an important role in the efficient capture and transfer of the virus to susceptible cells. With an aim of generating DCs from a renewable source for HIV-1 studies here we evaluated the capacity of hES cell derived CD34 cells to give rise to DCs which can support HIV-1 infection. Results Undifferentiated hES cells were cultured on S17 mouse bone marrow stromal
