 AB    Successful treatment of human immunodeficiency virus infection may
       ultimately require targeting of hematopoietic stem cells. Here we used
       retroviral vectors carrying the ribozyme gene to transduce CD34+ cells
       from human fetal cord blood. Transduction and ribozyme expression had no
       apparent adverse effect on cell differentiation and/or proliferation.
       The macrophage-like cells, differentiated from the stem/progenitor cells
       in vitro, expressed the ribozyme gene and resisted infection by a
       macrophage tropic human immunodeficiency virus type 1. These results
       suggest the feasibility of stem cell gene therapy for human
       immunodeficiency virus-infected patients.
