Abstract
A process and means for the design and the optimization of retroviral vectors transducing human .beta.-globin gene and .beta.-Locus Control Region (.beta.-LCR) derivatives, hereafter referred to as [.beta.-globin/LCR] retroviruses, which successfully meet the following criteria required for gene therapy applications: (1) stability of proviral transmission (low frequency of rearrangements similar to retroviral vectors considered stable in the art) upon infection of cell-lines and murine bone marrow cells, (2) improved viral titer, thereby allowing successful infection of bone marrow cells, and (3) high erythroid expression of the transduced human .beta.-globin gene, are described, along with specific constructs.
