library_construction_protocol: Cells were lysed in TRIzol reagent (Invitrogen). PureLink RNA extraction kit with on-column DNase treatment (Invitrogen) was used to isolate high quality RNA from Hofbauer cells. Total RNA-seq libraries were generated with NEBNext® Ultra™ II Directional RNA Library Prep Kit for Illumina (NEB #E7760L) and NEBNext® rRNA Depletion Kit with sample purification beads (NEB #E6350) with an input amount of 200 ng total RNA per sample. Libraries were pooled and sequenced on an Illumina NovaSeq SP flowcell in paired-end 150 bp format (Illumina, San Diego, CA) to a read yield between 70 – 80 million reads (equivalent to 35 – 40 million clusters).
