Figure 2From: Hyaluronic acid affects the in vitro induction effects of Synthetic PAMPS and PDMAAm hydrogels on chondrogenic differentiation of ATDC5 cells, depending on the level of concentration PCR analyses concerning the effects of the PAMPS and PDMAAm gel surfaces on ATDC5 cells cultured in the maintenance medium. Each bar shows the mean and the standard deviation from 6 samples. Expression of type-2 collagen (Col-2) and aggrecan genes was significantly greater on the PAMPS and PDMAAm gels than on the polystyrene surface (“PS w/o insulin” shown in the graph), and the former expression levels were comparable to the levels of the cells cultured on the polystyrene surface in the differentiation medium with insulin (“PS w/ insulin” shown in the graph).Back to article page
