Abstract
The retina, a complex neuronal tissue with over 100 distinct cell types, has not been fully explored in terms of mRNA alternative splicing at the single-cell level. Addressing this, we employed single-cell RNA sequencing using both short-read and long-read high-throughput methodologies. We profiled approximately 30,000 mouse retina cells, yielding 1.54 billion Illumina short-reads and 1.4 billion long nanopore sequencing reads. Our analysis identified 44,325 transcript isoforms, of which 55% are novel and 17% exhibit cell-class-specific expression. Notably, while many isoforms were found across different cell types, their distribution varied significantly among them. This study substantially enriches our understanding of the retinal transcriptome isoform diversity, paving the way for deeper investigations into alternative splicing's role in retinal biology and associated diseases.
