Figure 2From: Hyaluronic acid enhances the effect of the PAMPS/PDMAAm double-network hydrogel on chondrogenic differentiation of ATDC5 cells Expression of type-2 collagen in ATDC5 cells cultured on the PAMPS/PDMAAm double-network (DN) gel and the polystyrene (PS) dish at 7 and 21 days of culture. The cells cultured on the DN gel formed nodules and were stained with an anti-type-2 collagen antibody (green). White scale bars show a length of 200 micrometers.Back to article page
