In the present study, an enzyme catalyzed in situ forming hydrogel based on tyramine conjugated tragacanth (TA-GT) was prepared and then utilized, as 3D scaffold, for in vitro chondrotic differentiation of human mesenchymal stem cells (hMSCs). The hydrogel was prepared by mixing of TA-GT, horseradish peroxidase (HRP) and hydrogen peroxide solution, using a double syringe equipped with a mixing chamber. Then, in vitro chondrogenic differentiation of the encapsulated hMSCs, after 21 days incubation in the presence of differentiation medium, were investigated. Hydrogel formation was obtained due to enzyme catalyzed oxidative coupling reaction between phenolic groups of tyramine groups. Viability of the encapsulated hMSCs was more than 90% and 75% after 2 h and 21 days of incubation. The expression of chondrocytic genes and sulphated glycosaminoglycan indicated that the encapsulated hMSCs differentiated to chondrocyte cells during in vitro differentiation time.
