AAV-shRNA-Ifitm1 treatment downregulated Ifitm1 expression in mouse limbal epithelium . A scRNA-seq assay was conducted using cells isolated from corneal/limbal tissues at three days after corneas were injured. scRNA-seq assay identified stem/early TA cell population using Gpha2, a limbal epithelial stem /eTA cell marker. In AAV-EV treated mouse eyes, NaOH injury increased the numbers of the stem/eTA cells compared to uninjured eyes. Such expansion of stem/eTA cell population following corneal injury was markedly reduced in AAV-shRNA-Ifitm1 treated eyes. This suggests a positive role of Ifitm1 in stem/early TA cell expansion after corneal injury.","dates":{"publication":"2025/05/19"},"accession":"GSE277598","cross_references":{"GSM":["GSM8525760","GSM8525761","GSM8525762","GSM8525763","GSM8525764","GSM8525765"],"GPL":["24247"],"GSE":["277598"],"taxon":["Mus musculus"],"PMID":["[40372397]"]}}
