Transport specificity for neutral and basic amino acids at maternal and fetal interfaces of the guinea-pig placenta

AUTOR(ES)
RESUMO

1. The unidirectional influx of amino acids into the guinea-pig syncytiotrophoblast was measured using a single circulation paired-tracer dilution technique which allows separate characterization of both fetal and maternal interfaces. An in situ preparation perfused through the fetal circulation was used to examine the fetal side, while an isolated preparation perfused through both the fetal and maternal circulations was used to study both interfaces simultaneously.
