Abstract

Exosomes are attractive as nucleic-acid carriers because of their favourable pharmacokinetic and immunological properties and their ability to penetrate physiological barriers that are impermeable to synthetic drug-delivery vehicles. However, inserting exogenous nucleic acids, especially large messenger RNAs, into cell-secreted exosomes leads to low yields. Here we report a cellular-nanoporation method for the production of large quantities of exosomes containing therapeutic mRNAs and targeting peptides. We transfected various source cells with plasmid DNAs and stimulated the cells with a focal and transient electrical stimulus that promotes the release of exosomes carrying transcribed mRNAs and targeting peptides. Compared with bulk electroporation and other exosome-production strategies, cellular nanoporation produced up to 50-fold more exosomes and a more than 10 3-fold increase in exosomal mRNA transcripts, even from cells with low basal levels of exosome secretion. In orthotopic phosphatase and tensin homologue (PTEN)-deficient glioma mouse models, mRNA-containing exosomes restored tumour-suppressor function, enhanced inhibition of tumour growth and increased survival. Cellular nanoporation may enable the use of exosomes as a universal nucleic-acid carrier for applications requiring transcriptional manipulation.

  • PTEN is commonly mutated in wide ranges of GBM, which may be a candidate for therapeutic intervention.

    “A tumour suppressor gene, like phosphatase and tensin homologue (PTEN), is commonly mutated in wide ranges of GBM, which may be a great candidate for therapeutic intervention27,54.”

    From Blood–brain-barrier-crossing lipid nanoparticles for mRNA delivery to the central nervous system (2025) · cites this paper as [27]

    The Results section ('Functional and pharmacokinetic evaluation of CNP generated exosomes'; page not specified) calls PTEN a commonly mutated tumour suppressor gene and tests it as a therapeutic target in two PTEN-deficient glioma models. The in vivo Results report inhibited tumour growth after PTEN-restoring treatment. The copy does not establish how widely PTEN is mutated specifically across GBM. (LLM, conf=0.83)

  • CNP technology increases exosome yield and mRNA amount within exosomes.

    “The CNP technology increases the exosome yield and the mRNA amount within the exosomes [110].”
  • CNP increased mRNA loading in exosomes by 100-fold compared to conventional electroporation methods.

    “In addition, this strategy increased mRNA loading in exosomes by 100-fold compared to conventional electroporation methods.”
  • CNP-treated exosomes from cells of the same origin have an increased mRNA encapsulation efficiency of 3-4 folds compared to exosomes produced endogenously without external stimuli.

    “Compared to exosomes produced endogenously without involving external stimuli, CNP-treated exosomes from cells of the same origin have an increased mRNA encapsulation efficiency of 3–4 folds.”
  • By modifying exosome CD47 with CREKA and CDX peptides, targeting ability was improved.

    “By modifying the exosome CD47 with these peptides, the targeting ability was improved.”

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.
