Abstract

Lentiviral vectors are useful experimental tools for stable gene delivery and have been used to treat human inherited genetic disorders and hematologic malignancies with promising results. Because some of the lentiviral vector components are cytotoxic, transient plasmid transfection has been used to produce the large batches needed for clinical trials. However, this method is costly, poorly reproducible and hard to scale up. Here we describe a general method for construction of stable packaging cell lines that continuously produce lentiviral vectors. This uses Cre recombinase-mediated cassette exchange to insert a codon-optimised HIV-1 Gag-Pol expression construct in a continuously expressed locus in 293FT cells. Subsequently Rev, envelope and vector genome expression cassettes are serially transfected. Vector titers in excess of 10 6 transducing units/ml can be harvested from the final producer clones, which can be increased to 10 8 TU/ml by concentration. This method will be of use to all basic and clinical investigators who wish to produce large batches of lentiviral vectors.

  • A method for generating clinical-grade stable packaging cell lines that continuously produce lentiviral vectors was reported.

    “Recently, a method for generating clinical-grade stable packaging cell lines that continuously produce lentiviral vectors was reported [65].”

    From Clinical use of lentiviral vectors (2018) · cites this paper as [65]

    The Abstract (page unavailable) reports a method for constructing stable packaging cell lines that continuously produce lentiviral vectors. But the Methods > Cell Culture section describes the derived lines as potentially for future clinical use; our copy does not establish that the lines generated were already clinical-grade. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • The reported method for generating stable packaging cell lines solved a key issue with lentiviral vector production found in previous studies, which was that plasmid transfection of the gag-pol cassette did not induce continuous high-level expression.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
