胚胎移植(ET)是生物学和实验动物研究中的一项有用技术。虽然目前已经明确了两细胞期大鼠胚胎的冷冻保存和受体大鼠的ET,但尚不清楚这些人工生殖技术和母体因素是否会影响后代的表型,特别是更高的脑功能。因此,我们使用具有高学习能力表型的东海高回避(THA)大鼠,评估了冷冻保存、ET和母体护理对后代学习行为的影响。我们发现,THA大鼠后代的高学习能力并没有复制ET后,以替代Wistar大鼠与低回避表型。此外,通过ET衍生大鼠交配获得的后代的特征表型与THA大鼠相似。与Wistar和THA大鼠的后代的产后交叉寄养调查表明,母亲的行为,包括产后护理和哺乳性状,没有不同的低回避Wistar大鼠和THA大鼠的母鼠之间,因此,学习行为保留在Wistar和THA大鼠后代。我们的结论是,后代的表型,虽然没有变化,有一个潜移默化的影响,对学习能力的ET-衍生THA大鼠通过宫内环境的收件人。
Embryo transfer (ET) to recipient female animals is a useful technique in biological and experimental animal studies. While cryopreservation of two-cell stage rat embryos and ET to recipient rats are currently well-defined, it is unknown whether these artificial reproductive techniques and maternal factors affect offspring phenotype, particularly higher brain functions. Therefore, we assessed the effects of cryopreservation, ET, and maternal care on learning behaviour of the offspring, using Tokai high avoider (THA) rats that have a high learning ability phenotype. We found that the high learning ability of THA rat offspring was not replicated following ET to surrogate Wistar rats with a low-avoidance phenotype. Additionally, the characteristic phenotype of offspring obtained through mating of ET-derived rats was similar to that of THA rats. A postnatal cross-fostering investigation with the offspring of Wistar and THA rats showed that maternal behaviour, including postnatal care and lactation traits, did not differ between the dams of low-avoidance Wistar rats and THA rats; therefore, learning behaviour was retained in both Wistar and THA rat offspring. We conclude that the offspring phenotype, although unchanged, has an imperceptible effect on the learning ability of ET-derived THA rats through the intrauterine environment of the recipient.
