Abstract

The main goal of this study was to assess the effect of different sterilization treatment for sterilization of decellularized kidney tissue. Rabbit kidneys were decellularized by the perfusion-based method using sodium dodecyl sulfate (SDS) and Triton X-100. Then, decellularized kidney slices were prepared and sterilized by an antibiotic cocktail, PAA (0.5 %, 1% and 1.5 %), 5KG γ-irradiation and 320-480 nm UV-irradiation. Histological evaluations, DNA quantification assay, MTT assay, scanning electron microscopy (SEM), mechanical test and bacterial and fungal culture tests were performed to determine the quality of decellularization and sterilization processes. The kidney slices were seeded by adipose-derived mesenchymal stem cells (ASCs) to assess the cell adhesion capability after treatment. The results of the current study indicated that PAA 0.5 % was the most efficient method to completely decontaminate rabbit decellularized kidney tissue while preserving the mechanical properties and main components of the matrix which are necessary for cell-matrix interaction and cell adhesion. The 5KG γ-irradiation was determined to be the most destructive sterilization method, with reduced the mechanical strengths as well as altered microstructure of the kidney matrix and no cell adhesion. In addition, UV-irradiation is not able to sterile the decellularized tissues. Therefore PAA 0.5 % sterilization method can be a powerful means for sterilization of biological scaffolds.

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.
