英文摘要 | The effects of preservation media for ovaries on in vitro maturation of porcine oocytes was studied. The cumulus-oocyte complexes (COCs) obtained from ovaries that had been preserved in three different media at various temperatures for different time intervals were cultured in the M199 maturation medium. The preservation media used were 0.9% saline solution, BCS (Braun-Collins solution) and Dulbecco’s phosphate buffered saline solution (PBS). Mature oocytes obtained from the ovaries preserved in three preservation media for 8 h were electrically activated. The activated oocytes were then cultured in the NCSU23 embryo culture medium for 16 h to observe activation, or for 144 h to observe embryo development. It was found that the preservation temperature significantly affected maturation of the porcine oocytes. A preservation temperature of about 25°C showed an optimal maturation rate for a preservation time of 8 h for the three preservation media. Although the preservation temperature was a major factor influencing the maturation rate, different preservation media at 25°C for 8 h also significantly affected the maturation rate, activation rate and embryo development. Among these three preservation media, PBS exhibited the highest cleavage rate indicating that PBS should be a better preservation medium for porcine ovaries at 25°C for 8 h or longer periods. |
