Description: Oviduct samples were collected from C57BL6 female mice at estrus, 0.5, 1.5, 2.5, and 3.5 days post coitus (dpc). Some females were mated with vasectomized male mice to induce pseudopregnancy. Then the oviducts were collected at 0.5, 1.5, 2.5, and 3.5 days of pseudopregnancy (dpp). Oviducts were dissected into Infundibulum + Ampulla (IA) or Isthmus + Uterotubal Junction (IU) regions. RNA sequencing was performed using Illumina Novaseq. Data were analyzed using Galaxy with trimmomatic, HISAT2 alignment, and featureCounts. n = 3 biological replicates.
