The gene regulating sequence of human collagen type Ⅰ is located at 5'end and first intron. The carriers of reporting gene was made, and the function of promoter, enhancer and inhibiter was examined in this study. On the basis of above work, MBP ectopic expression carriers were further built. The result laid a foundation for investigating the feasibility, and validity to specially express MBP gene of human nervous system, in tendon fibroblast.

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.
