摘要:

胚胎植入前基因检查(preimplantation genetic testing,PGT)不仅在人类生殖医学上发挥着重要作用,还在畜牧业上有重要的应用。家畜良种繁育过程中,PGT可用于引入理想性状,增强遗传多样性,提高整体畜群质量。通过选择具有特定遗传特征的胚胎,可以提高诸如抗病性、生产力和寿命等性状,促进畜牧育种计划进步。基于基因组评估的胚胎选择通过增加选择强度,缩短世代间隔,从而增加遗传增益。然而,当前PGT主要采用有创检查,这会对胚胎结构完整性造成破坏。因此,最大程度地保存胚胎结构完整性能够更好地维持其活力,目前已开始探究采用无创检查(ni-PGT)来评估胚胎植入前的发育潜能,包括检测囊胚液和胚胎培养基中无细胞DNA(cell-free DNA,cfDNA)。本文概述了PGT和无创胚胎进行PGT方法,整理了现有PGT在畜牧业及人类辅助生殖方面的应用进展,以期为ni-PGT在畜牧领域广泛应用提供理论参考。

Abstract:

Preimplantation genetic testing (PGT) not only plays a significant role in human reproductive medicine but also has important applications in animal husbandry. In the process of breeding superior livestock, PGT can be used to introduce desirable traits, enhance genetic diversity, and improve the overall quality of the herd. By selecting embryos with specific genetic characteristics, traits such as disease resistance, productivity, and lifespan can be enhanced, thus promoting progress in animal breeding programs. Embryo selection based on genomic evaluation increases selection intensity and shortens generation intervals, thereby increasing genetic gain. However, current PGT mainly employs invasive methods, which can damage the structural integrity of embryos. Therefore, preserving the structural integrity of embryos to the greatest extent can better maintain their viability. Currently, non-invasive PGT (ni-PGT) methods are being explored to assess the developmental potential of embryos before implantation, including the detection of cell-free DNA (cfDNA) in blastocoel fluid and embryo culture medium. This article summarizes the methods of PGT and non-invasive PGT for embryos, and compiles the application progress of existing PGT in animal husbandry and human assisted reproduction, with the aim of providing theoretical references for the wide application of ni-PGT in the field of animal husbandry.
