Physiologische Qualitätsbeurteilung von Embryonen anhand des Aminosäurenprofils

  • H.M. PictonEmail author
  • H.J. Leese


Die Entwicklung und Verwendung von Aminosäureprofilen in der Klinik wird Fortpflanzungsmediziner in die Lage versetzen, die Embryoselektion auf solide quantifizierbare biologische Merkmale statt auf subjektive Kriterien zu stützen. Auf der Basis des Umsatzes von 5 Schlüsselaminosäuren können morphologisch ähnliche Embryonen im Teilungsstadium, die metabolisch „stumm“, aber fähig sind, eine zygotische Genomaktivierung und Entwicklung zuf Blastozyste zu durchlaufen, von solchen unterschieden werden, die metabolisch aktiv, aber dazu bestimmt sind, einen Teilungsstopp zu erleiden. Nunmehr bedarf es prospektiver klinischer Studien, um den Wert der Erstellung eines Aminosäurenprofils für den elektiven Transfer eines einzelnen Embryos zu bestätigen und die Beteiligung chromosomaler Depletionen oder Additionen an geänderten Stoffwechselprofilen von Embryonen in vitro weiter zu erforschen.
