Abstract

Image-guided, lobe-specific hydrodynamic gene delivery to liver was assessed in pigs. The procedure involved image-guided insertion of a balloon catheter to the hepatic vein of the selected lobe from the jugular vein and hydrodynamic injection of plasmid DNA using a newly developed computer-controlled injection device. We demonstrated that the impact of the procedure was regional with minimal effects on neighboring lobes. Level of gene expression resulted from the procedure was 10(7) relative light units (RLU)/mg in the targeted lobes and 10(2)-10(5) RLU/mg in the nontargeted lobes 4 hours after hydrodynamic injection of pCMV-Luc plasmids. Occlusion of blood flow in the inferior vena cava (IVC) or IVC plus portal vein (PV) was effective in elevating hydrodynamic pressure in the targeted vasculature but did not enhance gene delivery efficiency. Physiological examination on pigs with IVC occlusion revealed transient decreases of blood pressure and respiration rate. Removal of occlusion from IVC resulted in a rapid and transient increase in heart rate. Occlusion of the PV and hepatic vein showed no effect on physiological and cardiac activities. No major changes in serum composition were observed. These results suggest that (i) image-guided, lobe-specific hydrodynamic procedure is effective for regional gene delivery to liver, (ii) blockade in IVC should be avoided for hydrodynamic gene delivery to the liver, and (iii) clinical application of hydrodynamic gene delivery to liver is feasible.

  • Porcine liver is stiffer than human liver, which may be attributed to histological differences between the two tissues.

    “They reported that porcine liver is stiffer than human liver, which may be attributed to the histological differences between the two tissues [53,54].”

    From Liver tissue engineering using decellularized scaffolds: Current progress, challenges, and opportunities (2024) · cites this paper as [53]

    The Results section, “Comparative liver histology of different animal species” (page unavailable), reports collagen-rich connective tissue around pig liver lobules but not human liver lobules. The Discussion (page unavailable) suggests that this structure restricts distention in pig liver. The paper does not directly compare the stiffness of porcine and human liver, so the claim of greater porcine stiffness goes beyond its findings. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • The main histological difference between porcine and human liver is the presence of a higher amount of collagen, especially in connective tissue septa that surround the lobules in pigs, while these septa are absent in human liver parenchyma.

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.
