Abstract

BACKGROUND & AIMS: The therapy of choice for end-stage liver disease is whole-organ liver transplantation, but this option is limited by a shortage of donor organs. Cell-based therapies and hepatic tissue engineering have been considered as alternatives to liver transplantation, but neither has proven effective to date. A regenerative medicine approach for liver replacement has recently been described that includes the use of a three-dimensional organ scaffold prepared by decellularization of xenogeneic liver. The present study investigates a new, minimally disruptive method for whole-organ liver decellularization and three different cell reseeding strategies to engineer functional liver tissue. METHODS: A combination of enzymatic, detergent, and mechanical methods are used to remove all cells from isolated rat livers. Whole-organ perfusion is used in a customized organ chamber and the decellularized livers are examined by morphologic, biochemical, and immunolabeling techniques for preservation of the native matrix architecture and composition. Three different methods for hepatocyte seeding of the resultant three-dimensional liver scaffolds are evaluated to maximize cell survival and function: (1) direct parenchymal injection, (2) multistep infusion, or (3) continuous perfusion. RESULTS: The decellularization process preserves the three-dimensional macrostructure, the ultrastructure, the composition of the extracellular matrix components, the native microvascular network of the liver, and the bile drainage system, and up to 50% of growth factor content. The three-dimensional liver matrix reseeded with the multistep infusion of hepatocytes generated ∼90% of cell engraftment and supported liver-specific functional capacities of the engrafted cells, including albumin production, urea metabolism, and cytochrome P450 induction. CONCLUSIONS: Whole-organ liver decellularization is possible with maintenance of structure and composition suitable to support functional hepatocytes.

Claims other papers make about this one

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

  • Enzymatic treatment, particularly involving nucleases and trypsin, is often combined with chemical detergents followed by various washing cycles for liver decellularization.

    “Hence, enzymatic treatment, particularly involving nucleases and trypsin, is often combined with chemical detergents followed by various washing cycles for liver decellularization [110,123,149,150].”
  • The biliary tree is maintained post-perfusion decellularization, requiring only reseeding by cholangiocytes to restore functionality.

    “Furthermore, the biliary tree is maintained post-perfusion decellularization, requiring only reseeding by cholangiocytes to restore functionality [110].”
  • Primary murine hepatocytes have demonstrated the ability to attach, grow, proliferate, and survive within decellularized rodent livers while retaining their morphology and function.

    “Primary murine hepatocytes are frequently used for recellularization experiments and have demonstrated the ability to attach, grow, proliferate, and survive within decellularized rodent livers while retaining their morphology and function [12,110,203].”
  • Soto-Gutierrez et al. demonstrated that a multistep infusion of cells via the portal vein resulted in a better parenchymal repopulation rate, with a cell engraftment rate of approximately 90%, and exhibited higher proliferative capacity as well as a superior functional profile of engrafted cells, including albumin production, CYP1A1/2 activity, and ammonia clearance, compared to direct parenchymal

    “For example, Soto-Gutierrez et al. demonstrated that a multistep infusion of cells via the portal vein resulted in a better parenchymal repopulation rate, with a cell engraftment rate of approximately 90 %, and exhibited higher proliferative capacity as well as a superior functional profile of engrafted cells, including albumin production, CYP1A1/2 activity, and ammonia clearance, compared to”
  • 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].”

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.
