RETROVIRAL VECTOR HYBRIDS AND THE USE THEREOF FOR GENE TRANSFER

摘要

The disclosure relates to replication defective retroviral vector hybrids characterized by the fact that they contain: ( a) in the leader region as U5 region and/or tRNA primer binding site, the U5 region and/or tRNA primer binding site of MESV; and (b) as U3 and R regions in 3'-LTR, the U3 and R regions from a Friend murine leukaemia virus (F-MuLV). The proposed hybrids are particularly suitable for effective gene transfer in haematopoietic stem cells.
