This represents the largest amniotic fluid transcriptomics study in normal pregnancy, reporting for the first time that single-cell genomic signatures can be tracked in the amniotic fluid and display complex patterns of expression during gestation. PRB researchers also demonstrate a role for alternative splicing in tissue-identity acquisition, organ development, and immune processes. The results herein may have implications for the development of fetal testing to assess placental function and fetal organ maturity.
