Bulk RNA-seq of adult pig and rat central canal–associated spinal cord cells

Bulk RNA sequencing was performed on central canal–associated spinal cord cells isolated from adult pig (Sus scrofa) and rat (Rattus norvegicus) spinal cords and expanded under ex vivo culture conditions. Libraries were sequenced on the Illumina NovaSeq 6000 platform using 150 bp single-end reads. Transcript abundances were quantified using Salmon (v1.x) against species-specific reference transcriptomes (pig: ss11; rat: rn6). This dataset enables cross-species analysis of transcriptional programs associated with proliferative activation and progenitor-associated states in the mammalian spinal cord.
