Comparative Eye Transcriptome Atlas

The Comparative Eye Transcriptome Atlas provides transcriptomic resources to study retinal evolution and physiology across non-mammalian vertebrates. We profiled retinas from four species using two complementary high-throughput approaches. Eight 10x Genomics Visium spatial transcriptomics datasets were generated from Anolis carolinensis (n = 2), Taeniopygia guttata (n = 4), Columba livia (n = 1), and Gallus gallus (n = 1), capturing spatially resolved gene expression with matched histology images. In parallel, six 10x Genomics Chromium Single Cell 3′ RNA-seq datasets were obtained from zebra finch (T. guttata) retinas to resolve cell-type–specific transcriptomes. Raw sequencing data (FASTQ) and processed outputs from SpaceRanger (Visium) and CellRanger (Chromium) are provided. Downstream integrated and annotated datasets can be explored interactively at https://linlab.au.dk/Damsgaard_lab/CETA/ and full Seurat objects are available on request.
