Abstract
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.
