Abstract

One approach of regenerative medicine to generate functional hepatic tissue in vitro is decellularization and recellularization, and several protocols for the decellularization of livers of different species have been published. This appears to be the first report on rat liver decellularization by perfusion under oscillating pressure conditions, intending to optimize microperfusion and minimize damage to the ECM. Four decellularization protocols were compared: perfusion via the portal vein (PV) or the hepatic artery (HA), with (+P) or without (-P) oscillating pressure conditions. All rat livers (n = 24) were perfused with 1% Triton X-100 and 1% sodium dodecyl sulphate, each for 90 min with a perfusion rate of 5 ml/min. Perfusion decellularization was observed macroscopically and the decellularized liver matrices were analysed by histology and biochemical analyses (e.g. levels of DNA, glycosaminoglycans and hepatocyte growth factor). Livers decellularized via the hepatic artery and under oscillating pressure showed a more homogeneous decellularization and less remaining DNA, compared with the livers of the other experimental groups. The novel decellularization method described is effective, quick (3 h) and gentle to the extracellular matrix and thus represents an improvement of existing methodology.

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?

  • The efficiency of decellularization via perfusion depends on the route of perfusion, perfusion direction, perfusion conditions, duration, type and concentration of decellularizing agents, and the size of the liver.

    “Importantly, the efficiency of decellularization via perfusion depends on various factors, including the route of perfusion (hepatic artery or portal vein or inferior vena cava), perfusion direction (antegrade or retrograde), perfusion conditions (controlled pressure and flow rate), duration of the perfusion, type and concentration of decellularizing agents, and the size of the liver [7,26,170].”
  • 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.
