转基因猪已经成为推动畜牧业和人类医学进步的宝贵工具。重要的是,胚胎的体外生产和操作是创建猪模型过程中的重要步骤。由于体外环境仍然是次优的,因此必须从几个角度检查猪胚胎培养系统以确定改进的方法。了解猪胚胎的代谢特征,并考虑与其他哺乳动物物种的比较是有用的优化培养基配方。此外,必须考虑到环境和母体或父亲因素产生的压力,以在体外产生健康的胚胎。在这篇综述中,我们逐步通过猪的体外卵母细胞成熟,受精和胚胎培养来评估当前培养系统的状况,并提出可以改进的地方。
Genetically modified pigs have become valuable tools for generating advances in animal agriculture and human medicine. Importantly, in vitro production and manipulation of embryos is an essential step in the process of creating porcine models. As the in vitro environment is still suboptimal, it is imperative to examine the porcine embryo culture system from several angles to identify methods for improvement. Understanding metabolic characteristics of porcine embryos and considering comparisons with other mammalian species is useful for optimizing culture media formulations. Furthermore, stressors arising from the environment and maternal or paternal factors must be taken into consideration to produce healthy embryos in vitro. In this review, we progress stepwise through in vitro oocyte maturation, fertilization, and embryo culture in pigs to assess the status of current culture systems and address points where improvements can be made.
