Abstract:
Objective To observe the effects of secreted protein,acidic and rich in cysteine (SPARC) on the expression of TGF-β1 and collagen type Ⅰ in cultured human keloid fibroblasts by real-time fluorescence quantitative RT-PCR.Methods In vitro keloid fibroblasts were stimulated by different concentrations of recombinant human SPARC,and with the control group for comparison,real-time fluorescence quantitative RT-PCR to detect expression of TGFβ1 and collagen type Ⅰ.Results Compared with the control group,the expression of TGF-β1 and collagen type Ⅰ was significantly increased in the experimental group.Conclusions SPARC could enhance the expression of TGF-β1 and collagen type Ⅰ in keloid fibroblasts significantly.
