Abstract

Orthotopic liver transplantation is the only available treatment for severe liver failure, but it is currently limited by organ shortage. One technical challenge that has thus far limited the development of a tissue-engineered liver graft is oxygen and nutrient transport. Here we demonstrate a novel approach to generate transplantable liver grafts using decellularized liver matrix. The decellularization process preserves the structural and functional characteristics of the native microvascular network, allowing efficient recellularization of the liver matrix with adult hepatocytes and subsequent perfusion for in vitro culture. The recellularized graft supports liver-specific function including albumin secretion, urea synthesis and cytochrome P450 expression at comparable levels to normal liver in vitro. The recellularized liver grafts can be transplanted into rats, supporting hepatocyte survival and function with minimal ischemic damage. These results provide a proof of principle for the generation of a transplantable liver graft as a potential treatment for liver disease.

  • Bioengineered livers produced with dECM scaffolds and liver-composing cells have been extensively developed to replace or regenerate injured liver tissues.

    “bioengineered livers produced with dECM scaffolds and liver-composing cells have been extensively developed to replace or regenerate injured liver tissues8,9.”

    From Bioengineered liver crosslinked with nano-graphene oxide enables efficient liver regeneration via MMP suppression and immunomodulation (2023) · cites this paper as [8]

    The Results and Discussion describe a decellularized liver matrix seeded with hepatocytes, with preliminary endothelial-cell seeding, for a transplantable graft. But the paper calls this a first step toward auxiliary liver grafts; it does not establish that such livers had been extensively developed or had replaced or regenerated injured liver tissue.

  • The enrichment of laminin in decellularized liver matrices has been explored with the aim of creating transplantable grafts.

    “The enrichment of laminin in decellularized liver matrices has been explored with the aim of creating transplantable grafts.[ 126 ]”

    From Bioactive scaffolds for tissue engineering: A review of decellularized extracellular matrix applications and innovations (2025) · cites this paper as [126]

    The Results section (Characterization of decellularized liver matrix; page unavailable) reports that laminin-β1 was retained in the decellularized matrix similarly to native liver, not that the matrix was enriched with laminin. The paper also reports developing and transplanting recellularized liver grafts in rats, so the graft objective is supported, but the claimed laminin enrichment is not. (LLM, conf=0.89)

  • Uygun's work yielded transplantable grafts from decellularized liver matrices that supported liver functions including albumin secretion, urea synthesis, and cytochrome P450 activity, and enhanced hepatocyte survival and function post-transplant.

  • Perfusion represents an ideal approach for decellularizing large, thick, compact organs like the liver.

    “Perfusion, which involves the infusion of chemical or biological agents through the cannulated intrinsic vascular system, represents an ideal approach for decellularizing large, thick, compact organs like the liver [7,12].”

    From Liver tissue engineering using decellularized scaffolds: Current progress, challenges, and opportunities (2024) · cites this paper as [12]

    The Results (Characterization of decellularized liver matrix; page unavailable) report successful whole-rat-liver decellularization by portal perfusion with SDS. The Discussion says this preserved liver architecture and vasculature. The paper does not establish that perfusion is the ideal approach for large, thick, compact organs generally. (LLM, conf=0.84)

  • 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].”

    From Liver tissue engineering using decellularized scaffolds: Current progress, challenges, and opportunities (2024) · cites this paper as [12]

    The Results (Recellularization of decellularized liver matrix; no page available) report that primary rat hepatocytes engrafted in decellularized rat livers and remained viable and functional. The Results (Transplantation of recellularized liver grafts; no page available) report retained normal morphology and hepatic function. The paper does not demonstrate that the hepatocytes grew or proliferated within the matrix. (LLM, conf=0.88)

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.
