RESULTS: The AF cells cultured in different substrates were morphologically undistinguishable. Toluidine blue staining showed that there was also no difference between AF cells cultured on flexible silicone membranes and in plastic plates. The cells growing in different substrates expressed the same levels of collagen typeⅠ,Ⅱ and aggrecan mRNA and integrin β1. AF cells grew well on silicone membranes.
