    The study developed tissue-engineered tubular grafts using bone marrow mesenchymal stem cells and silk fibroin/chitosan scaffolds for urinary diversion.

  • 2

    BMSCs differentiated into urothelium-like cells, expressing specific proteins, and were successfully implanted in a rabbit model.

  • 3

    Histological analyses showed complete epithelialization by week 8 in the experimental group, with positive staining for mature epithelial markers.

  • 4

    All rabbits in the experimental group survived, demonstrating patent outflow tracts without complications, unlike control grafts that collapsed.

  • 5

    The study suggests BMSCs as a viable cell source for urinary tissue engineering, potentially replacing gastrointestinal segments in clinical practice.
