To evaluate the long-term effects of oocyte cryopreservation on the health of the first filial generation (F1), we used B6D2F1 mice for oocyte collection, in vitro fertilization, and breeding. The female F1 mice born from the offspring of fresh mature oocytes (control group) and from the offspring of vitrified oocytes with traditional vitrification medium (VM group) and new improved vitrification medium (2P10E7D group) were maintained until 14-15 months of age for behavioral tests and 16-17 months of age for physiological analyses. Behavioral indexes, including anxiety-like status, discrimination ability, learning and memory ability, were investigated. Physiological indexes including body weight, body fat, heart rate, blood pressure, and blood lipids were also analyzed. In our results, the behavioral indexes, body weight, body fat, heart rate, blood pressure, total cholesterol (TC), high-density lipoprotein cholesterol (HDL), and low-density lipoprotein cholesterol (LDL) did not show significant differences among the three groups. However, the triglyceride (TG) level of the VM group was higher than that of the 2P10E7D group. Moreover, compared with the control group, both the VM group and the 2P10E7D group showed greatly increased diastolic blood pressure. This study is the first to report that oocyte vitrification might affect metabolic physiological indexes via transgenerational inheritance rather than behaviors related to anxiety-like status and cognitive ability. Furthermore, different vitrification media might have differential transgenerational effects.

卵母细胞玻璃化冷冻对老年第一子代小鼠行为和生理指标的影响

为了评估卵母细胞冷冻保存对第一代 (F1) 健康的长期影响,我们使用 B6D2F1 小鼠进行卵母细胞采集、体外受精和繁殖。新鲜成熟卵母细胞后代(对照组)和传统玻璃化培养基(VM组)和新型改良玻璃化培养基(2P10E7D组)玻璃化卵母细胞后代出生的雌性F1小鼠被维持至14-15月龄行为测试和 16-17 个月大的生理分析。考察焦虑样状态、辨别能力、学习记忆能力等行为指标。还分析了体重、体脂、心率、血压和血脂等生理指标。在我们的结果中,行为指标、体重、体脂、心率、血压、总胆固醇(TC)、高密度脂蛋白胆固醇(HDL)和低密度脂蛋白胆固醇(LDL)在三组之间没有显着差异。然而,VM组的甘油三酯(TG)水平高于2P10E7D组。而且,与对照组相比,VM组和2P10E7D组的舒张压均显着升高。本研究首次报道卵母细胞玻璃化可能通过跨代遗传而不是与焦虑样状态和认知能力相关的行为影响代谢生理指标。此外,不同的玻璃化介质可能具有不同的跨代效应。和低密度脂蛋白胆固醇 (LDL) 在三组之间没有显示出显着差异。然而,VM组的甘油三酯(TG)水平高于2P10E7D组。而且,与对照组相比,VM组和2P10E7D组的舒张压均显着升高。本研究首次报道卵母细胞玻璃化可能通过跨代遗传而不是与焦虑样状态和认知能力相关的行为影响代谢生理指标。此外,不同的玻璃化介质可能具有不同的跨代效应。和低密度脂蛋白胆固醇 (LDL) 在三组之间没有显示出显着差异。然而,VM组的甘油三酯(TG)水平高于2P10E7D组。而且,与对照组相比,VM组和2P10E7D组的舒张压均显着升高。本研究首次报道卵母细胞玻璃化可能通过跨代遗传而不是与焦虑样状态和认知能力相关的行为影响代谢生理指标。此外,不同的玻璃化介质可能具有不同的跨代效应。VM 组和 2P10E7D 组的舒张压均显着升高。本研究首次报道卵母细胞玻璃化可能通过跨代遗传而不是与焦虑样状态和认知能力相关的行为影响代谢生理指标。此外,不同的玻璃化介质可能具有不同的跨代效应。VM 组和 2P10E7D 组的舒张压均显着升高。本研究首次报道卵母细胞玻璃化可能通过跨代遗传而不是与焦虑样状态和认知能力相关的行为影响代谢生理指标。此外,不同的玻璃化介质可能具有不同的跨代效应。
