title: Regulation of colony stimulating factor-1 (CSF-1) in endometrial cells: glucocorticoids and oxidative stress regulate the expression of CSF-1 and its receptor c-fms in endometrial cells.
abstract: OBJECTIVE
  To evaluate the regulation and expression of CSF-1 and its receptor c-fms in endometrial cells.
  
  
  METHODS
  In vitro study.

  METHODS
  In vitro experimental study.
  
  
  METHODS
  The effect of glucocorticoid and oxidative stress on the expression of CSF-1 and c-fms in endometrial cells.
  
  
  RESULTS
  Cultured nonmalignant EM42 cells not only express CSF-1 and c-fms but are also capable of responding to exogenous CSF-1. We have also seen that glucocorticoids can regulate the expression of CSF-1/c-fms in endometrial cells. Furthermore, this study shows that oxidative stress plays a significant role in the induction of CSF-1 and its receptor c-fms.
  
  
  CONCLUSIONS
  The results suggest that CSF-1 may promote the growth of nonmalignant endometrial cells in both an autocrine and paracrine manner and that endometrial cells under oxidative stress induce CSF-1 and c-fms.
