Abstract

At this time, the only definitive treatment of hepatic failure is liver transplantation. However, transplantation has been limited by the severely limited supply of human donor livers. Alternatively, a regenerative medicine approach has been recently proposed in rodents that describe the production of three-dimensional whole-organ scaffolds for assembly of engineered complete organs. In the present study, we describe the decellularization of porcine livers to generate liver constructs at a scale that can be clinically relevant. Adult ischemic porcine livers were successfully decellularized using a customized perfusion protocol, the decellularization process preserved the ultrastructural extracellular matrix components, functional characteristics of the native microvascular and the bile drainage network of the liver, and growth factors necessary for angiogenesis and liver regeneration. Furthermore, isolated hepatocytes engrafted and reorganized in the porcine decellularized livers using a human-sized organ culture system. These results provide proof-of-principle for the generation of a human-sized, three-dimensional organ scaffold as a potential structure for human liver grafts reconstruction for transplantation to treat liver disease.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Albumin immunostaining was lower after 7 days of media perfusion compared to day 4, attributed to shear stress caused by media flow.

    “Furthermore, they observed that albumin immunostaining was lower after 7 days of media perfusion compared to day 4, attributed to shear stress caused by media flow.”

    From Liver tissue engineering using decellularized scaffolds: Current progress, challenges, and opportunities (2024) · cites this paper as [198]

    The Results (Recellularization; page not provided) report that albumin immunostaining decreased considerably after seven days of perfusion culture compared with day four. The Discussion proposes optimizing perfusion flow to decrease shear stress in future studies, but does not establish shear stress as the cause of the staining decrease. (LLM, conf=0.88)

  • The biliary network tree is confirmed to be intact after decellularization by scan electron microscopy, corrosion cast, dye perfusion, and contrast radiography; only reconstruction by bile duct cells is necessary.

    “Fortunately, the biliary network tree is confirmed to be intact after decellularization by scan electron microscopy, corrosion cast, dye perfusion, and contrast radiography; only reconstruction by bile duct cells is necessary [12,110,170,198].”

    From Liver tissue engineering using decellularized scaffolds: Current progress, challenges, and opportunities (2024) · cites this paper as [198]

    The Results section (Vascular and Bile Duct Morphology; page unavailable) reports that bile ducts were mostly intact after decellularization, but notes disruption of smaller branches and contrast retention at the biliary tree’s periphery. The Discussion says biliary epithelial cells would be needed for bile drainage, but does not establish that adding those cells is the only reconstruction needed. The paper also does not show that each of the four listed techniques confirmed an intact biliary tree. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • Yagi et al. reported that around 47.8% of reseeded hepatocytes were apoptotic by day 7 in decellularized porcine livers.

    “Importantly, they reported that around 47.8 % of reseeded hepatocytes were apoptotic by day 7.”

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.
