In vitro aging of porcine oocytes

Popis výsledku v původním jazyce

Porcine oocytes matured in vitro develop in various ways if they are further cultivated. In our studies these oocytes were cultured for 1 to 5 days (in vitro aging). During the 1st day of aging, most of them remained at the stage of metaphase II (98%). Then many oocytes underwent the spontaneous parthenogenetic activation. The portion of activated oocytes reached the peak after 2 or 3 days of aging in vitro (39 or 45%). The portion of fragmented oocytes peaked at the same time (28%). During subsequent aging in vitro (day 4 and 5), the portion of lysed oocytes significantly increased (30 or 37%). The highest portion of spontaneously activated parthenogenetic embryos at a pronuclear stage (35%) was observed during the 2nd day of aging in vitro. These pronuclear embryos had mainly one polar body with two pronuclei (47% of all pronuclear embryos) or two polar bodies with one pronucleus (38% of all pronucleus embryos). During the 3rd and 5th day of in vitro aging, there was a significant in
