Effects of TGF-?1 on production of a-SMA and extracellular matrix in flexor tendon sheath fibroblasts / 中国矫形外科杂志

[Objective]To examine the effects of TGF-?1 on the production of ?-SMA and extracellular matrix in flexor tendon sheath fibroblasts. [Methods]Sheath fibroblasts were obtained from rabbit flexor tendons.Cell culture was supplemented with 5ng/ml of TGF-?1.After 48 hours incubation,the production of a-SMA was assayed by Western-Blot.The productions of collagen I and fibronectin in supernatants culture were examined using ELISA.[Results]Treatment with TGF-?1 significantly stimulated a-SMA production in flexor tendon sheath fibroblasts (P
