This study introduces a comprehensive placental transcriptome reference developed through long-read RNA sequencing, uncovering a level of transcriptional complexity previously unrecognized in this organ. By identifying over 37,000 high-confidence isoforms, including thousands of previously unannotated transcripts, the researchers challenge the notion that the placenta is a genomic void. The authors demonstrate that this tissue-specific reference significantly reduces quantification uncertainty in existing datasets compared to generic adult-tissue annotations. Utilizing this refined…
