Influence of Environmental Factors on the Metabolism of Glucose by Preimplantation Mouse Embryos in vitro

Abstract

The metabolism of glucose by late pre implantation mouse embryos was studied in a variety of media whose composition had been changed to reflect the environmental conditions in the uterus more closely than do standard culture media. The effects of combinations of energy substrates, the presence or absence of amino acids and the level of potassium in the medium were investigated.
