Abstract

In a cell-free approach to regenerative therapeutics, transient application of paracrine factors in vivo could be used to alter the behavior and fate of progenitor cells to achieve sustained clinical benefits. Here we show that intramyocardial injection of synthetic modified RNA (modRNA) encoding human vascular endothelial growth factor-A (VEGF-A) results in the expansion and directed differentiation of endogenous heart progenitors in a mouse myocardial infarction model. VEGF-A modRNA markedly improved heart function and enhanced long-term survival of recipients. This improvement was in part due to mobilization of epicardial progenitor cells and redirection of their differentiation toward cardiovascular cell types. Direct in vivo comparison with DNA vectors and temporal control with VEGF inhibitors revealed the greatly increased efficacy of pulse-like delivery of VEGF-A. Our results suggest that modRNA is a versatile approach for expressing paracrine factors as cell fate switches to control progenitor cell fate and thereby enhance long-term organ repair.

  • Conclusive data have also been presented for mRNA as a platform for protein (replacement) therapies.

    “Conclusive data have also been presented for mRNA as a platform for protein (replacement) therapies (Kormann et al, 2011; Kariko et al, 2012; Zangi et al, 2013; Thess et al, 2015; Balmayor et al, 2016).”

    The Abstract and Results report that VEGF-A modRNA produced a therapeutic protein and improved cardiac outcomes in a mouse model of myocardial infarction. This supports mRNA as a potential platform for protein-based therapy, but the paper does not demonstrate protein replacement therapy specifically or establish conclusive efficacy across such therapies.

  • Conventional unmodified mRNAs are inferior to molecules harboring specific nucleoside modifications, but the picture changes dramatically with sophisticated sequence-engineering.

    “Our work principally confirms that conventional unmodified mRNAs are inferior to molecules harboring specific nucleoside modifications as suggested by various recent reports,23,24,25,26,27 however, the picture changes dramatically with a sophisticated sequence-engineering.”
  • Intramyocardial injection of mRNA expressing human VEGF-A with RNAiMAX decreased morbidity of mice with myocardial infarction following repair of heart function.

    “For example, an intramyocardial injection of mRNA expressing human vascular endothelial growth factor A (VEGF-A) with RNAiMAX decreased the morbidity of mice with myocardial infarction following the repair of heart function.[201]”

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.
