This study aimed to evaluate the chondrogenic potential of alginate gel loaded transforming growth factor beta 1(TGF-β1) and bone marrow derived stem cells(BMSCs). We, based on previous in vitro experiment, encapsulated cell and TGF-β1 into alginate bead and transplanted on the dorsum of nude mouse subcutaneously. The implantations were harvested and evaluated by histology through H&E, Alcian Blue, Safranin-O and immunohistochemistry( IHC) and immunofluorescence(IF) staining. These results presented that the alginate bead incorporated with TGF-β1 and BMSC is promising for cartilage tissue engineering application and that specially is more helpful to chondrogenesis in a limited area than alginate with nothing or the alternative TGF-β1 or BMSC.
