Resumen
Los avances en los equipos ecográficos y la realización de técnicas invasivas durante el primer trimestre del embarazo han permitido un acercamiento sin precedentes al entendimiento del desarrollo embrionario. Durante el primer trimestre del embarazo, el análisis de las muestras procedentes de suero materno, celoma extraembrionario, saco vitelino y saco amniótico, obtenidas tanto en humanos como en modelos animales, han puesto de manifiesto los cambios sucesivos que se producen en las características fisicoquímicas de estos líquidos en respuesta al desarrollo del propio embrión y sus anejos.
Palabras Clave:

Abstract
Advances in ultrasonographic equipment and the use of invasive techniques in the first trimester of pregnancy have allowed unprecedented knowledge of embryo development. In the first trimester of pregnancy, analysis of samples from maternal serum, extraembryonic celom, vitelline sac and amniotic sac both from humans and from animal models have revealed the successive changes in the physiochemical characteristics of these fluids in response to the development of the fetus and the extraembryonic compartments.
Key words:
Transvaginal ultrasound
Vitelline sac
Extraembryonic celom
Celocentesis
