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.
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.
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.
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.
作者研发了用于软骨细胞和骨髓间充质干细胞(BM-MSCs)植入的自体纤维蛋白基支架,并与商用纤维蛋白胶相比,评估了细胞在自体纤维蛋白基支架中的活力。
将软骨细胞和BM-MSCs接种到自体纤维蛋白基支架和商用纤维蛋白胶中。在第1天和第7天评估细胞活力和增殖情况。在6周时,用苏木精-伊红(H&E)染色评估组织学,并用阿尔辛蓝、番红O、甲苯胺蓝和II型胶原染色评估软骨基质形成情况。观察支架的固定情况。
软骨细胞和BM-MSCs在商用纤维蛋白胶中无法存活。自体纤维蛋白基支架中的软骨细胞和BM-MSCs能够增殖,并在6周时在阿尔辛蓝、番红O、甲苯胺蓝和II型胶原染色下合成软骨基质。固定强度极佳。
所研发的自体纤维蛋白基支架可作为软骨细胞和BM-MSCs植入的支架,具有在关节镜下植入软骨细胞和BM-MSCs的潜力。
