Abstract:
:The aim of this study was to evaluate the efficiency of different media in the in vitro culture of bovine preantral follicles that were used either fresh or following slow freezing treatment. Frozen and fresh noncultured or cultured ovarian fragments were processed for histological, viability, and cell proliferation analyses. For cryopreservation, a solution containing 1.5 M ethylene glycol was frozen in a programmable biological freezer. After thawing, a portion of the samples was destined for frozen controls. The remainder were cultured in vitro for 5 days in three media: α-MEM, McCoy, or M199. Samples from these culture media were collected on days 1 and 5 for quantification of reactive oxygen species (ROS) and for hormonal assays. In fresh-cultured tissues, the percentage of morphologically normal follicles was significantly higher when cultured in M199 compared to that in the other media. In frozen-cultured tissues, McCoy medium was significantly superior to the other media, and was the only treatment that helped in maintaining the viability similar to fresh and frozen controls. Upon quantification of the nucleolus organizer region, we observed greater proliferation of granulosa cells in the frozen-cultured tissues with McCoy medium, and lesser proliferation in fresh-cultured tissues only with α-MEM. In frozen-cultured tissues, ROS levels were highest at day 1 and progressively reduced during culture, independent of the media used. In conclusion, under the conditions used in this study, the M199 and McCoy media are recommended for the culture of follicles derived from fresh and frozen ovarian tissues, respectively.
