title: [Effect of c-ski on biological behavior of rat skin-derived fibroblast].
abstract: OBJECTIVE
  To observe the effect of oncogene c-ski on the cell viability, myofibroblast differentiation and type I collagen secretion of rat skin-derived fibroblast.
  
  
  METHODS
  In situ expression of c-Ski in fibroblast was detected by immunohistochemistry. After cells transfected with c-ski gene, the changes of cell proliferation was measured with the method of MTT, the type I collagen secretion and myofibroblast differentiation were checked with the methods of immunohistochemistry and RT-PCR.
  
  
  RESULTS
  There was obvious expression of c-Ski in fibroblast, which mainly located in nucleus. c-ski could promote cell proliferation in a dose-dependent manner, and also decrease mRNA and protein expression of type I collagen, but had no effect on myofibrblast differentiation.
  
  
  CONCLUSIONS
  The roles of c-ski promoting cell viability and decreasing collagen secretion may have an important significance in accelerating wound healing and reducing scar formation.
