    Doty et al. in this technical report generate and characterize a helper-free, packaging system composed entirely of feline leukemia virus subgroup C (FeLV-C) components. Using this new packaging system, the authors demonstrate that they can produce higher titer vectors than existing gammaretroviral packaging systems

    Repetitive Busulfan Administration After Hematopoietic Stem Cell Gene Therapy Associated with a Dominant HDAC7 Clone in a Nonhuman Primate

    Safety studies designed to evaluate genotoxicity of retroviral gene therapy agents may require long-term follow-up, hampering their progression to the clinic. Here, Xie et al. tested the hypothesis that hematopoietic stress in a nonhuman primate model of ex vivo hematopoietic stem cell gene therapy accelerated proliferation and the detection of clonal dominance
