In this study, the effect of nCDHA on chondrogenic differentiation of rat adipose-derived adult mesenchymal stem cells in alginate gel was evaluated. nCDHA/alginate composites containing different amounts of nCDHA were prepared and used to encapsulate rat ADAS. The chondrogenic differentiation of ADAS was enhanced after 7 days and the total collagen content increased after 14 days at 500 ppm of nCDHA.
