    • The question is to increase the quality and safety of the media used in embryo and cell manipulations by means of supplementation, in the manipulation medium, by one or several of the following compounds: synthetic hyaluronan ( sHA), phospholipids or unsaturated fatty acids obtained from soybean seeds (PLFA), replacing others which are habitually added to embryo manipulation media and which produce potential damage and/or contamination by viruses, prions, endotoxins, etc., this being important with regard to the quality of the embryos or cells which it is desired to generate, both for the production of transgenic animals, for animal production, and for cell therapy or assisted reproduction; achieving a reduction in adhesiveness and an increase in viscosity, without losing the fluidity of the medium; this is essential in micro-manipulations such as ICSI, nuclear transfer, embryo biopsies, the micro-injection of cells into embryos in pre-implantational stages, or cell fusion.
    • 问题是通过在操作介质中通过一种或几种以下化合物来增加在胚胎和细胞操作中使用的培养基的质量和安全性:合成透明质酸(sHA),磷脂或不饱和脂肪酸 大豆种子(PLFA),替代习惯上添加到胚胎操纵介质中并且由于病毒,朊病毒,内毒素等而产生潜在的损害和/或污染的其它物质,这对于胚胎或细胞的质量而言是重要的 期望产生用于生产转基因动物,用于动物生产,以及用于细胞治疗或辅助繁殖; 实现粘合性的降低和粘度的增加,而不会损失介质的流动性; 这在微操作如ICSI,核转移,胚胎活组织检查,细胞注入胚胎在植入前阶段或细胞融合中是微不足道的。
