形态学和卵裂率仍然是胚胎评估的主要依据。然而,用于该应用的一些附加技术正在研究中。这些包括测量胚胎培养基中的葡萄糖、乳酸盐、丙酮酸盐或氨基酸水平,评估胚胎的耗氧量,基因组和蛋白质组学分析,以及最近的胚胎代谢组学分析。随着世界范围内辅助生殖周期的增加,快速和非侵入性地识别最佳胚胎移植的能力的提高仍然是生殖医学的一个关键目标。最近的研究表明,使用光学和非光学光谱的胚胎培养基的代谢组学分析可以为当前的胚胎评估策略提供有用的辅助手段,并提供对具有增加生殖潜力的胚胎表型的洞察。
Morphology and cleavage rate remain the mainstay of embryo assessment. However, a number of additional technologies for this application are under investigation. These include the measurement of glucose, lactate, pyruvate or amino acid levels in the embryo culture media, assessment of oxygen consumption by the embryo, genomic and proteomic profiling, and most recently, analytical examination of the embryonic metabolome. As the number of assisted reproduction cycles increases worldwide, improvements in the ability to quickly and non-invasively identify the best embryos for transfer remain a critical goal for reproductive medicine. Recent studies suggest that metabolomic profiling of embryo culture media using optical and non-optical spectroscopies may provide a useful adjunct to the current embryo assessment strategies and provide insight into the phenotype of embryos with increasing reproductive potential.
