title: Media composition: amino acids and cellular homeostasis.
abstract: Amino acids are beneficial for the developing preimplantation embryo and therefore form an important component of culture media. This chapter will critically review the importance of amino acids for preimplantation embryos and the impact of this research for the development of sequential culture media used in many assisted conception units. The advantages of culturing embryos in a full complement of amino acids, at close to physiological concentrations will be considered. Moreover, the noninvasive measurement of amino acid turnover by individual embryos, a method which holds great promise to assess developmental competency prior to transfer, will also be discussed. Thus, this chapter highlights the fundamental role of amino acids for the metabolic and homeostatic regulation of the preimplantation embryo.
