Objective To investigate the feasibility of the complex of the fibrin sealant (FS) and the bone marrow mesenchymal stem cells（MSCs） to createanew cartilage in the nude mice by the issue engineering technique. Methods T he MSCs were isolated from healthy humans and were expanded in vitro. And then the MSCs were induced by the defined medium containing the transforming growth factor β1 (TGF-β1), dexamethasone, and ascorbic acid. The biomechanical properties of the chondrocytes were investigated at 7 and 14 days. The MSCs induced for 7days were collected and mixed with FS. Then, the FSMSCs mixture was injectedby a needle into the dorsum of the nude mice in the experimental group. In the tw o control groups, only FS or MSCs were injected respectively. The specimens were harvested at 6 and 12 weeks，and the ability of chondrogenesis in vivo was inve stigated by the gross observation, HE, Alcian Blue staining, and type Ⅱ collagen immunohistochemistry. Results The MSCs changed from a spindlel ike fibroblastic appearance to a polygonal shape when transferred to the defined medium, and couldbe induced to express the chondrocyte matrix. After an injection of the mixture , the cartilage-like tissue mass was formed, and the specimens were harvested from the mass at 6 and 12 weeks in the experimental group. The tissue mass at 6 we eks was smaller and relatively firm in texture, which had a distinct lacuna structure. And glycosaminoglycan (GAG) and Type II Collagen expressions were detecte d. The tissue mass at 12 weeks was bigger, firmer and glossier with the mature c hondrocytes lying in the lacuna structure. The positive Alcian blue and Collagen II immunohistochemistry stainings were ber at 12 weeks than at 6 weeks. But there was no cartilage-like tissue mass formed in the two control groups. Conclusion This study demonstrates that the fibrin sealant and the bone marrow mesenchymal stem cells can be successfully used in a constructing technique for the tissue engineered injectable cartilage.
