title: Involvement of macrophage colony-stimulating factor (M-CSF) in the function of follicular granulosa cells.
abstract: OBJECTIVE
  To evaluate the role of macrophage colony-stimulating factor (M-CSF) in steroidogenesis by luteinized granulosa cells (GCs) and to examine the effect of FSH, E(2), and P on the production of M-CSF by GCs.
  
  
  METHODS
  In vitro experimental study.
  
  
  METHODS
  University hospital with an IVF-intracytoplasmic sperm injection program.
  
  
  METHODS
  Forty infertile women who underwent intracytoplasmatic sperm injection.
  
  
  METHODS
  The GCs obtained from these patients during oocyte retrieval were cultured and then treated with different concentrations of M-CSF, FSH, E(2), or P for 72 hours.
  
  
  METHODS
  The M-CSF concentrations were determined by ELISA, and the concentrations of E(2) and P were measured by enzyme immunoassay.
  
  
  RESULTS
  The M-CSF secretion of GCs was enhanced by FSH or E(2) in vitro in a dose-dependent manner but was unaffected by P. On the other hand, M-CSF elicited a production of E(2) and P by GCs in a dose-dependent manner in the presence or absence of FSH.
  
  
  CONCLUSIONS
  The results suggest that the growth factor M-CSF might have an important role in ovarian function.
