Title

THE EFFECTS OF VITRIFICATION ON SPINDLE APPARATUS OF IN VITRO MATURED GERMINAL VESICLE IN MICE

Pages

  209-215

Abstract

 Background: Routine oocytes cryopreservation remained an elusive technique in the wide ranges of available assisted reproductive technologies. The MICROTUBULEs of oocytes are vulnerable to cryoprotectants and thermal change during cryopreservation.Objective: The effects of a VITRIFICATION protocol were investigated on the spindle and chromosome configurations of MICE oocytes cryopreserved at the germinal vesicle stage.Materials and Methods: Germinal vesicle with cumulus cells were transferred to VITRIFICATION solution which was composed of 30% (v/v) ethylene glycol, 18% Ficoll-70 and 0.3 M Sucrose either by single step or in step-wise way. Following VITRIFICATION and in vitro maturation (MII), the matured oocytes were immonostained for meiotic spindles and chromosomes, before visualization using fluorescent microscopy. Results: A statistically significant increase was observed in the survival and maturation rate in step-wise VITRIFICATION (88.96% and 71.23% respectively) compared to single step VITRIFICATION (70.6% and 62.42% respectively) (p<0.05). Normal spindle morphology after VITRIFICATION-thawing in step-wise VITRIFICATION group (77.26%) was higher than single step VITRIFICATION group (64.24%) but lower than control group (94.75%) (p<0.05).Conclusion: The results suggest that VITRIFICATION with step-wise procedure on MICE GERMINAL VESICLE OOCYTEs has positive effects on survival and maturation rate and normal spindle configuration compare with single step VITRIFICATION procedure.
