title: Human cord blood mononuclear cell transplantation for the treatment of premature ovarian failure in nude mice.
abstract: OBJECTIVE
  This study explored the potential of human cord blood mononuclear cell (HCMNC) transplantation as a treatment for premature ovarian failure (POF) in a nude mouse model.
  
  
  METHODS
  Female nude mice were randomly divided into three groups; a normal control group (n = 35), a POF group (POF plus vehicle, n = 35) and a POF plus cell transplantation group (HCMNCs were implanted into the ovaries, n = 35). HCMNCs were isolated by Ficoll density gradient centrifugation and labeled with BrdU. Four weeks after transplantation, the nude mice were sacrificed to determine serum levels of E2, FSH and LH as indicators of ovarian function, and the ovaries were examined both histologically and immunochemically.
  
  
  RESULTS
  The transplanted HCMNCs survived in the transplantation group and were detected by BrdU. In the transplantation group, serum levels of E2 significantly increased while serum levels of FSH and LH significantly decreased compared to the POF control group. Additionally, the transplantation group had a recovery in follicle number.
  
  
  CONCLUSIONS
  HCMNCs can be successfully transplanted into the ovaries of nude mice and can improve ovarian function in POF.
