Objective: The authors developed the autologous fibrin-base scaffold for chondrocytes and bone marrow mesenchymal stem
cells (BM-MSCs) implantation and evaluated cells viability in autologous fibrin-base scaffold comparing to commercial fibrin
glue.
Material and Method: The chondrocytes and BM-MSCs were seeded into autologous fibrin-base scaffold and commercial
fibrin glue. The cell viability and proliferation were evaluated at 1 and 7 days. The histology were evaluated with hematoxylineosin
(H&E) staining and cartilaginous matrices formation with Alcian blue, Saffanin-0, Toluidine blue, and Collagen type II staining at 6 weeks. The fixation of the scaffolds was observed.
Results: The chondrocytes and BM-MSCs could not survive in commercial fibrin glue. The chondrocytes and BM-MSCs in
autologous fibrin-base scaffold could proliferate and synthesize the cartilaginous matrices on Alcian blue, Saffanin-0, Toluidine blue, and Collagen type II staining at 6 weeks. The fixation strength is excellent.
Conclusion: The developed autologous fibrin-base scaffold can be used as the scaffold for chondrocytes and BM-MSCs
implantation with potential to implant chondrocytes and BM-MSCs arthroscopically.
