Despite its importance, the spatial transcriptome of the FT's distinct anatomical regions (fimbria, infundibulum, ampulla, and isthmus) remains underexplored. Using the GeoMx Digital Spatial Profiler (DSP) and a targeted ~1800 gene panel, we analyze premenopausal FT epithelium, identifying region-specific gene expression patterns. Our analysis reveals upregulation of mature ciliated cell markers (FOXJ1, MLF1, SPA17, and CTSS) approaching the fimbria, elevated ROS and apoptosis-related transcripts (TXNIP, PRDX5, BAD, GAS1) in the distal FT, and a switch in cell-cell adhesion transcripts (CDH1, CDH3) along the distal-to-proximal axis.
